Essay Sample on Man Is a Social Animal

Essay Sample on Man Is a Social Animal Man Is a Social Animal The first time when man was defined as a social animal was back in the ancient times. Aristotle wrote in his Politics: Hence it is evident that the state is a creation of nature and that man by nature is a political animal. Political here can be interpreted as social due to the meaning of the Greek word politikos, which meant the social aspect as well. Later, Baruch Spinoza also stated that men were social animals, and that it was because of their nature – they get from society much more convenience than injury, as they are not able to live in solitude. This definition can be interpreted in different ways, and for me it also has a meaning. It is a well-known fact that women and men perceive this world in different ways. They think and even see differently, which is why there are often certain misunderstandings that result in major disappointments. What is interesting, women often call the men animals when they are angry with them, and indeed they are right. Men have more resemblance with some animals than women do. For instance, as predators, they have the so-called tunnel vision. Women, in their turn, have well-developed peripheral sight. Men are more straightforward and practical and have many other characteristics that are different from women. And it is the way females should perceive them – as a kind of social animal that needs attention and their love. Women and men complement each other and should understand their differences in order to make use of them in the right way. They should enjoy the process of getting to know their partners, and not feel upset about it. If we consider our problems in relationships from this perspective, everything will be much better in our lives.

Essay about The Reality of Affirmative Action - 2443 Words

In the United States justice is defined as equal treatment of all citizens under the law. When one citizen is treated unfairly, an injustice has been committed against all people. It is the duty of Americans to make sure such injustices are eliminated. Affirmative Action is one such program whose purpose is to make sure that equal citizens are treated equally under the law. In today’s society it is imperative that all people regardless of race or gender are given equal opportunity in the admissions and job applications processes. Affirmative Action was designed to create this equality. The history of Affirmative Action ultimately began two hundred years ago with the founding of our nation. The Constitution, which is the basis of all†¦show more content†¦However, this act mistakenly led Americans to the assumption that the problem of racism would be solved. It soon became evident that anyone who is educated to perform a task, can do so. Finally the playing field appeared to be level. Unfortunately, however, everyone was not willing to play fairly or equally. Hence, the necessity to have policies such as Affirmative Action arose. The phrase â€Å"Affirmative Action† was first used as a term to describe racial discrimination in Executive Order No. 10,925 issued by President John F. Kennedy in 1961. Kennedy issued this order in hopes that federal contractors would take affirmative action and ensure that job applicants and employees were treated â€Å"without regard to their race, creed, color, or national origin â€Å" (Pasour, 1989). Yet, few people actually knew what the order stated and what exactly its requirements were. It soon became apparent that this Order was actually a concept. According to a recent review made by the White House to President Clinton, Congress defines Affirmative Action as, â€Å"any effort taken to expand opportunity for women or racial, ethnic and national origin minorities by using membership in those groups that have been subject to discrimination as a consideration† (Congress, 1995).

Community Knowledge Building And Self Regulated Learning Education Essay Free Essays

string(156) " a box or circle that is connected to one or more other constructs via directed discharge, stand foring the relationships between the constructs concerned\." Background In Hong Kong, it has already been a long clip that schooling puts the chief focal point on persons ‘ abilities, temperaments and chances without profoundly researching the possibility of larning through community interaction. Normally merely formal cognition and incontrovertible accomplishments are taught in traditional schoolrooms. The bulk of this sort of cognition is inert that does non promote deep thought and enquiry. We will write a custom essay sample on Community Knowledge Building And Self Regulated Learning Education Essay or any similar topic only for you Order Now There is no mechanism for pupils to get expert-learning accomplishments. In add-on, informal or silent cognition is by and large ignored in school course of studies, though it is every bit of import as the formal cognition. The acquisition aims are besides crystalline to pupils. Students are occupied with undertakings and activities but they do non hold a clear thought about the grounds why they have to make those undertakings and activities. Problem 2: Pedagogical Paradigm Shift due to the Introduction of the NSS Curriculums Since 2009, the course of studies of most secondary schools have undergone a dramatic alteration due to the acceptance of the New Senior Secondary ( NSS ) course of studies. Two major alterations are the debut of broad surveies and project-based acquisition. The broad surveies subject enables pupils to do connexions among different subjects, examine issues from a assortment of positions, and construct personal cognition of immediate relevancy to themselves in the modern-day universe. On the other manus, project-based acquisition ( PBL ) aims to enable pupils to build cognition through developing their independent acquisition capablenesss, generic and collaborative accomplishments. It is obvious that the new course of studies emphasise on the cultivation of abilities of pupils to incorporate information gathered to build their ain cognition independently and collaboratively. However, most instructors and pupils are still non prepared for this polar alteration and experience perplexed about the new manner of instruction and acquisition. Problem 3: The Problems of the Commonly Used Learning Platforms Even though some Hong Kong schools understand the jobs of the traditional permissive instruction attack, good acquisition platforms that can carry through the demands of this new acquisition environment are rare in the market. Despite that many schools have installed computing machines with Internet entree in schoolrooms, there is no obvious difference in pupil larning quality between this sort of computer-supported schoolrooms and the traditional 1s. Intentional acquisition and expertness development.can barely be fostered in this sort of schoolroom scenes. In order to better larning quality and effectivity, some schools in Hong Kong have been following certain learning platforms for about ten old ages, yet they can merely let pupils to upload their work, download stuffs mandated by instructors, station messages to or read messages from electronic notice-boards, etc.. The platforms merely act like electronic information depositories that can non truly assist pupils to larn and build cognition on their ain or collaboratively, non to advert that the user interfaces are non easy-to-use in general. This sort of larning platforms contradicts the e-learning systems suggested by Angehrn, Nabeth and Roda ( 2001 ) . They claimed that e-learning should be extremely personalised, learner-centric, societal, active, synergistic, connected to scholars ‘ ends, supportive of uninterrupted acquisition and so on. Research of Existing Learning Platforms Supporting Collaborative Learning Sing the issues mentioned above, pupils in Hong Kong need a learning platform that can supply utile and effectual installations for them to pull off and build cognition, and larn collaboratively and continuously. The platform should besides assist them to do better usage of the bing on-line resources and manage and consolidate the information they have obtained for self-regulated acquisition. After researching preliminarily on bing acquisition platforms, there are three major computing machine supported collaborative work/learning ( CSCW/L ) systems available for instruction intents: FLE3, Synergeia and Knowledge Forum. FLE3 ( Leinonen et al. , 2002 ) , which is an unfastened beginning platform developed under the ITCOLE undertaking, entails a depository, a forum and a shared workspace called WebTop tool, Knowledge Building tool and Jamming tool severally. The last tool allows scholars to do usage of all sorts of multimedia digital artifacts. Synergeia ( Stahl, 2004 ) is besides designed within the ITCOLE undertaking that provides free licences for educational establishments. It portions paperss and informations through depositories ( the Basic Support for Cooperative Work system ) and forums ( Instant Messages ) severally in an asynchronous environment. The most singular tool is MapTool that enables a group of participants to make concept map collaboratively and synchronously. The confab tool is besides synchronal. Knowledge Forum was initiated by Marlene Scardamalia and Carl Bereiter. They have proposed that schools should be restructured as cognition edifice community based on the thought that larning, expertness cultivation in peculiar, requires enormous attempt and societal support that is non accessible in the first-order school environment. Students should get non-asymptotic acquisition accomplishments, i.e. , learn to continuously accommodate to alterations in the environment caused by others ‘ version. This procedure will invariably do parts to the corporate cognition of a school community, transforming the school into a second-order environment. Multimedia Learning A acquisition platform that can steer pupils efficaciously to build cognition from assorted sorts of information, particularly the multimedia one ( Shank, 2005 ) , is of paramount importance. Van Merrienboer ( 1999 ) proposed some guidelines of bringing of instructions in multimedia acquisition environments. He considered multimedia larning in web-based environments really important in the approaching hereafter as it facilitates distributed distance bringing and combines presentation and communicating installations. He believed that multimedia acquisition can be used to back up competency-based acquisition, and effectual, efficient and appealing collaborative acquisition. The multimedia capablenesss of all of the three platforms literally satisfy the guidelines. Concept Maps The MapTool of Synergeia allows participants to build corporate cognition through pulling construct maps: a graphical artifact that expresses cognition of scholars in a signifier that can be understood easy. The development of construct maps was initiated by Novak and Gowin ‘s ( 1984 ) research refering human acquisition and cognition building. In a construct map, besides called cognition map, a construct is normally placed inside a box or circle that is connected to one or more other constructs via directed discharge, stand foring the relationships between the constructs concerned. You read "Community Knowledge Building And Self Regulated Learning Education Essay" in category "Essay examples" The relationships are described by verbs normally. The constructs are contrived hierarchically with the most general constructs at the top of the map. The construction of a construct map is dependent on its context. Concept maps holding similar constructs can change from one context to another and are extremely idiosyncratic. Concept maps can be used to mensurate the cognition of a individual about a subject in a specific context. Therefore, construct maps constructed by different people on the same subject must be different. In the same sense, there is no such a thing as the â€Å" right † construct map about a peculiar subject, as there can be many available right representations of the subject. Concept function has assisted people of different ages obtain cognition in assorted Fieldss. When constructs and associating words are carefully chosen, these maps are powerful tools for detecting niceties of significance. Each construct map allows its Godhead to do usage of a virtually limitless set of associating words to demo how significances can be developed. There are no limitations on what words can be used to organize constructs or associating phrases. Concepts are normally nouns and associating phrases verbs. It is recommended to utilize as few words as possible for constructs and associating verbs. Associating phrases can show any types of relationships and are non limited to a defined set. Knowledge Building Knowledge Forum is designed harmonizing to the 12 Knowledge Building Principles proposed by Marlene Scardamalia and Carl Bereiter. It is a collaborative acquisition platform operated in a networked environment. It can work on both wired and wireless webs and users can entree it via the Internet. The model of Knowledge Forum is cross-sector, cross-age and cross-cultural. It has been used in instruction, wellness attention and concern communities in the Americas, Asia, Australia, Europe, and New Zealand. This reflects that the sociocognitive and cultural procedures underlying cognition acquisition and cognition creative activity are basically the same that are applicable to knowledge builders of all sectors, ages, and civilizations. The 12 Knowledge Building Principles are as follows: Real Ideas, Authentic Problems Ideas are every bit existent as touchable things. Learners are much more interested in existent life jobs than textbook jobs and mystifiers. Knowledge Forum fosters a civilization for scholars to work with thoughts creatively. Improvable Ideas All thoughts are improvable. Learners can actively better their ain thoughts and those in the community if they are encouraged to take hazards without being afraid to attest ignorance and have ague and unconstructive unfavorable judgment. Knowledge Forum allows continual betterment, alteration and theory polish. Idea Diversity Idea diverseness is indispensable to the development of cognition promotion as it creates a rich environment for thoughts to germinate into new and more refined signifiers. Knowledge Forum facilitates associating thoughts in different notes and positions together to advance interaction and productive usage of thought diverseness. Rise Above New syntheses of cognition can be obtained by unrelentingly working with improvable and diversified thoughts. High-order thought can be cultivated. In Knowledge Forum, rise-above notes and positions enable participants to larn accommodating progressive alterations in the environment. Epistemic Agency Learners are responsible for their cognition promotion that can be stimulated by the thoughts of other community members. They learn how to pull off their acquisition by puting ends and programs, inquiring inquiries, and measuring accomplishment. Knowledge Forum offers characteristics like scaffolds that help scholars synthesise high-ranking cognition by utilizing a assortment of epistemic footings such as speculation, admiration, speculate, etc.. Community Knowledge, Collective Responsibility Community accomplishments are valued more than single accomplishments. Participants portion duty for the overall cognition promotion in the community. Knowledge Forum provides an unfastened and collaborative environment that allows community members contribute conceptual artifacts that can be linked together effectual for future mention. Democratizing Knowledge All participants, including the more and less talented, are empowered to prosecute in cognition invention in Knowledge Forum. Every member strive for cognition promotion in a joint venture mode. Symmetric Knowledge Advancement It can be achieved from cognition exchange between members of different sorts of intelligence in a community as to give cognition is to acquire cognition. Knowledge Forum supports practical trials and co-construction of positions across user groups, both within and between communities. Permeant Knowledge Building Knowledge edifice utilizing Knowledge Forum can be carried out in and out of school through the Internet. Constructive Uses of Authoritative Beginnings Authoritative beginnings such as intelligence and multimedia stuffs found on the Internet can be attached to Knowledge Forum that can be acted as the foundation for cognition builders to progress community cognition. Knowledge Building Discourse Knowledge Forum accommodates discourse of cognition edifice communities that refines and transforms knowledge through the dianoetic patterns of the community. Embedded and Transformative Assessment Knowledge Forum allows a community to explicate its ain internal appraisal, which is both more bespoke and flexible than external appraisal Research Focus After comparing the chief characteristics of the three collaborative CSCL/W tools, it is blunt that Knowledge Forum emphasizes deeply on the procedure of community cognition edifice based on rules like improvable thoughts and progressive job work outing. It should be a more executable declaration for instructors and pupils to manage the approaching pedagogical paradigm displacement than the other two. It is perceived that Fle3 is simply designed as a package of depository, forum and shared workspace without important emphasis on the procedure of collaborative cognition building. Refering Synergeia, it is empowered by the notable construct maps that are widely accepted as a really effectual manner for cognition building. Nevertheless, the rise-above and build-on characteristics of Knowledge Forum maximize the learning capacity of each scholar through community attempt that triumph the concept-organising belongings of construct maps. Largely significantly, there are already many instructors rehearsing cognition edifice teaching methods utilizing Knowledge Forum in many topographic points. Apart from Toronto, Hong Kong has the largest instructor community giving excessive attempt to learning pupils collaborative larning accomplishments. However, the instructors who have experience in utilizing Knowledge Forum reported some insufficiency of the acquisition platform. For case, when a instructor wants to read a certain sort of messages, such as inquiries, he/she has to shop through all the notes straight in the present design. It is one of the grounds why it is non really easy to measure pupils ‘ parts. Sometimes a subscriber may desire to hold a list of his/her ain parts so that he/she can size up the acquisition procedure ; however, this map is non available in the current version. Research Aims The aims of this research are as follows: To look into extensively how Knowledge Forum can assist pupils build community cognition. To understand the jobs faced by instructors and pupils in utilizing Knowledge Forum, particularly those refering assessing pupils ‘ acquisition advancement and public presentation. To research a set of appropriate web and database engineering, particularly knowledge and information visual image, that is utile to strengthen the functionality of Knowledge Forum, particularly assessment tools that can avail instructors to measure pupils ‘ parts. To develop a paradigm of back uping tools that can reenforce Knowledge Forum sing appraisal, information storage and retrieval. To measure the quality and public presentation of the paradigm. Relevant Literature and Guiding Framework Knowledge Building and Problem Solving through Knowledge Forum Scardamalia and Bereiter believe that a school should be a topographic point for knowing acquisition and expertness cultivation. However, traditional schooling merely tackle seeable parts of cognition, i.e. , formal cognition and incontrovertible accomplishments. These sorts of inert cognition rarely touch pupils ‘ idea and behavior and utile informal/tacit cognition is seldom embraced in traditional school course of studies. Furthermore, in a traditional school, many instructors project their focal point on undertakings and activities without underlying the associated acquisition aims, so pupils are by and large incognizant of cognition aims behind the undertakings and activities they are supposed to make. Scardamalia and Bereiter point out pupils can accomplish knowing larning merely if they actively try to achieve a cognitive aim. Therefore, the current schooling system merely benefits those with high persons ‘ abilities, temperaments and chances, merely those alleged â€Å" bright † pupils are able to prise into the â€Å" secrets † of those undertakings and activities. Expertness cultivation in schools is besides of paramount importance, i.e. , pupils should be able to larn to be an expert-like scholar who processes progressive job work outing accomplishments. It is believed that job work outing accomplishments can be achieved through meaningful acquisition that metacognitive cognition is obtained by agencies of self-acting procedures. Richard and Wittrock put frontward seven instructional methods that stimulate job resolution: load-reducing, structure-based, schema-activation, productive, guided find, mold and learning thought. The first six methods train pupils to be domain job convergent thinkers while the last one enhances their general job work outing capablenesss. There are four characteristics of successful learning believing accomplishments plans: focal point on the most chiseled accomplishments, contextualize the accomplishments within reliable undertakings, personalise the accomplishments through societal interaction and language-based tr eatment of job resolution procedures, and speed up the accomplishments that pupils can larn with lower-level accomplishments. Simply expressed, Richard and Wittrock suggest that general expertness or job work outing accomplishments can be transferred from instructors to pupils based on dogmas similar to those 12s knowledge edifice rules advocated by Scardamalia and Bereiter. However, traditional schooling offers no mechanisms for instructors to reassign their expertness to pupils, so most pupils can non come on into expert-like scholars through reinvestment of mental resources released from following progressive job work outing methods such as form acquisition and automaticity. Scardamalia and Bereiter impulse that, with the drift of engineering, schools should be transformed into cognition edifice communities. The discourse framed by this sort of sociocognitive procedure transcends the barriers of didactic instruction and child/activity-centred cognition development. The advancement of the acquisition accomplished through cognition edifice discourse should be able to be orchestrated and mediated alternatively of the unpredictable acquisition advancement in traditional schooling. In add-on, all members in a school community, including both instructors and pupils, should take up corporate cognitive duty which â€Å" refers to the status in which duty for the success of a group attempt is distributed across all the members instead than being concentrated in the leader † ( p. 68 ) . Every community member should understand the cognition required by the community and do certain others know what they are supposed to cognize. In a cognition edifice discourse, a pupil referee can hold their cognition advanced from groking the parts made by other pupils in the community, so it is one of the inducements for pupils to take part in the discourse. Once a pupil makes a choice part, he/she gets acknowledgment and regard from other community members. The desire of being recognized and respected, together with the craving for doing outstanding impact on the community, may be two of the other motives. A to the full well-designed equal reappraisal system is indispensably required and the discourse should be near to pupils ‘ personal lives: â€Å" pupils work together to do sense of the universe around them and work towards progressing their ain province of cognition and that of the category † . The features of a successful cognition edifice discourse are â€Å" concentrate on jobs and deepness of understanding † , â€Å" decentralized, unfastened cognition environments for corporate apprehension † and â€Å" productive interaction within loosely conceived knowledge-building communities † ( p.274 ) . Technology plays a critical function in carry throughing a successful cognition edifice discourse. Knowledge Forum and its former version, Computer-Supported Intentional Learning Environment ( CSILE ) , have a community database at the Centre of a schoolroom discourse. Students ‘ thoughts can be extended to a broader cognition edifice community if necessary. In the discourse environment, pupils act as both writers and referees who can lend their thoughts by making text or graphical notes, hunt bing notes, and form notes into more complex informational constructions. Auto-notification through electronic mails will be sent to writers when others comment on their notes. The note-writing environments are specially designed for participants to specify enquiries as jobs alternatively of subjects. Discourses are carried out through saying theories and information for progressing theories. The scaffold map provides participants with phrases refering cognitive procedures, such as â€Å" I need to understand † , â€Å" My theory † , â€Å" A better theory † , â€Å" This theory can non explicate † , â€Å" Put our cognition together † , to call a few, that help participants contour discourses. The frequent usage of these theory-building footings can assist scholars tackle expert-like acquisition accomplishments that can be employed in their day-to-day lives. Knowledge Forum and CSILE besides pinpoint intentionality as scholars deliberately submit jobs of what they require to understand and asseverate justifications for linked attached. The knowing scholars can larn how to do determinations and deploy diag nostic procedures. Knowledge Forum and CSILE render a decentralized and unfastened discourse environment that reverses â€Å" the instructor initiates, pupil responds, teacher evaluates form for unwritten and written discourse † . By using a distributed theoretical account, information fluxing between participants is non audited by a cardinal authorization. Since different pupils possess different sorts of cognition, the cognition exchanges can be really productive. Students of different ages and abilities can take portion in the same discourse. Students with better viva voce or written linguistic communication accomplishments can non rule the discourse as the other pupils can border their thought by pulling diagrams or edifice on information in others ‘ notes or external resources. Those who are non familiar with the subject can lend to the community by inquiring inquiries and composing contemplations. The inefficient turn-tasking job in normal schoolroom treatments is automatically elimi nated as discourses in Knowledge Forum are held asynchronously over a computing machine web or the Internet. Students can compose their statements at any coveted clip and have all the clip they want to explicate the statements, without force per unit area like that happened in an unwritten treatment. This encourages pupils to print independent idea and polish their ain thoughts and those in the community, ensuing in progressive self-acting acquisition and job work outing preparation. Information / Knowledge Visualisation Some users reported that the current design of Knowledge Forum is non really intuitive to utilize, particularly for complex undertakings and ill-structured capable affairs. The new coevals of knowledge/information visual image engineering seems to be an effectual solution. The purpose of information visual image is to supply knowledge-based entree to information resources and aid users in doing sense of the resources they are looking for during information retrieval. On the other manus, the end of cognition visual image is to help pupils in acquisition and job resolution by supplying tools to further externalised knowledge. There are many good practiced information visual image techniques available, such as landscape metaphors, cartograms, ticket clouds, etc.. Some pedagogues claim that these techniques can assist users understand the information better. In the context of cognition building, apprehension of information is non sufficient, pupils need to be exposed to the information in different ways and be able to lucubrate a personal experience from it. Some other similar tools using visual image techniques have besides been developed in recent old ages, like Topic Maps Strand Map, VisIT ( Visualization of Information Tool ) , Model-It, Microworlds, etc.. Some web hunt engines even implement explorative hunts with the aid of information visual image techniques to polish user hunt questions. Users can now transport out explorative hunts on the WWW through consecutive loops on the ocular interfaces of these tools. Examples are KartOO, UJIKO, Crokker, Simploos, Quintura, oSkope, News Map, etc.. It is evident that educational tools using cognition visual image engineering can help pupils in undertaking topics like broad surveies to a great extent as this sort of topics require pupils to larn from resources in assorted subjects and develop capacities to construction and organize their cognition and acquisition stuffs for effectual learning direction, non to advert that cognition from different topics and spheres is complex, interconnected and ill-structured in a complex mode.

Childhood Animal Cruelty and Interpersonal Violence

Question: Describe about the growing consciousness of the link between animal abuse and interpersonal violence? Answer: With the growing consciousness of the link between animal abuse and interpersonal violence, most of the job is yet to be done in education and collaboration (McEwen et. al. 2014). As per the study made by experts, animal wellbeing law enforcement, domestic violence and child welfare agencies are working jointly more and more in appreciation of the link the undeniable bind flanked by animal maltreatment and brutality towards people, chiefly within the family (Gullone 2014). Researchers have recognized and documented that hostility towards people, chiefly within the family. Researchers have recognized and documented that violence towards animals can be both a module and an indication of a child spousal and elder exploitation. For an instance, in a landmark 1983 study, Deviney studied fifty-three families who met the officially authorized criteria for child abuse and neglect. Sixty percent of these families abused or neglected companion animals (Gullone 2014). In eighty-eight percent of the families where there was abuse of the children, there was animal abuse. In a Canadian study, fifty-six percent of pet-owning women seeking refuge in womens shelters reported that their abuser had threatened or had harmed their pet. Of those women with children and pets, sixty-five percent believed the children were aware of the abuse, and impacted by it. This study, and others from the domestic violence field, consistently show that women delay leaving abusive situations because of fears for a pet's safety (Schwartz et. al. 2012). Many womens shelters have arrangement s with local animal shelters or veterinary hospitals to provide temporary housingfor their pets. Hostility towards family pets is a way that abuser exert power and control over their other victims, who may be children, spouse, or elders. Threatening or hurting the pet may be used as a warning. Next time it could be you. Threats may be used as leverage. Fear for the pet keeps family members (spouse, child or elder) from disclosing the abuse and exposing the abuser. Forcing the victim to witness cruelty to their pet is emotional abuse. Children who hurt animals may be acting out of their own experience, i.e., what they observe, or what they undergo themselves, at home.

Free Essays on Natural Rate of Unemployment

Natural Rate of Unemployment When national income changes, the amount of employment and that of unemployment change as well. Unemployment follows a cyclical path, increasing during times of recession and decreasing in times of business expansion. The unemployment rate does not, show any important long-term trend over time. In macroeconomics, scholars name between the natural rate of unemployment made up by frictional and structural unemployment and the rate of cyclical unemployment. The unemployed are those who are without jobs and those who are searching for jobs. The unemployed are often measured as numbers of persons and sometimes as rates, expressed as percentages of the total labor force (Mishkin, 1995).

Free Essays on Natural Rate of Unemployment Free Essays on Natural Rate of Unemployment Natural Rate of Unemployment When national income changes, the amount of employment and that of unemployment change as well. Unemployment follows a cyclical path, increasing during times of recession and decreasing in times of business expansion. The unemployment rate does not, show any important long-term trend over time. In macroeconomics, scholars name between the natural rate of unemployment made up by frictional and structural unemployment and the rate of cyclical unemployment. The unemployed are those who are without jobs and those who are searching for jobs. The unemployed are often measured as numbers of persons and sometimes as rates, expressed as percentages of the total labor force (Mishkin, 1995).

Globalization and Internation Financial Crisis Essay

Globalization and Internation Financial Crisis - Essay Example This consolidation of global relationships is at the level of  individuals,  companies,  institutions  and countries (Campenhout and Cassimon, 2012).  The main causes of the process of globalization are the  technical progress in the communications and transportation sections, as well as, the  political  decisions on  liberalization  of  world trade. The study of International Finance is of particular significance in today’s globalized financial marketplace. International finance is a branch of  international economics and focuses on the monetary side of the international  economy. The subject matter of international finance is useful for students of economics, finance and business studies.  Ã‚  It is theorized that increasing globalization has played a role in creation of a wave of international financial crises in contemporary times (Schmukler and Vesperoni, 2006). The paper critically evaluates the supposition of globalization’s role in in ternational financial crisis and assesses the question whether international financial stability is feasible in an increasingly globalised economy. In addition, the paper critically appraises international financial crisis and ensuing policy responses to maximize economic and welfare consequences.   Discussion The degree of change brought about by the globalization of financial systems has been termed as financial globalization  by several researchers. Globalization of financial systems leads to the creation of a regional market integration of external financing.  According to Mishkin (2009), the financial aspect of  globalization  has three dimensions: geographical aspect of financial globalization refers to mobility of capital from one country to another, functional aspect of globalization relates to  capital markets which are compartmentalized through shifts in money markets and  stock markets. Obadan (2006) mentions that under the influence of financial globalizati on, global financial institutions are created, as well, like the  IMF, World Bank  and the European Community. Globalization’s effect on international financial markets also includes deregulation, abolition of  exchange controls  and restrictions on capital movements. Globalization also encourages financial innovation, disintermediation and direct access operators to funding without going through  intermediaries (Cline, 2010). The impacts of globalization on the financial systems are dealt under heads: Market Development Financial globalization has facilitated the financing of companies and that the  balance of payments. This has eliminated barriers to capital flows and has given an unprecedented boost to  financial markets worldwide (Rose, Prasad and Terrones, 2009). Today financial information is processed and disseminated around the  world, which leads to increased speculations in the financial markets and a high  volatility  of  capital round the glo be.  This provides a flow of investment opportunities based on  economic factors (Mishkin, 2009). These effects are sometimes seen as uncontrollable by the regional banking system  and the  international fina

A Formal Business Letter to The Rose Theatre Kingston Essay

A Formal Business Letter to The Rose Theatre Kingston - Essay Example As a larger company with profits above  £1.5M you may be taxed at 30% of profit per annum. Another salient point is the advantage that British theatres have in their attraction for tourists. Consider that technology now allows relatively inexpensive advertising on a wider, international scale thanks to the Internet. The inclusion of your theatre on tourist group itineraries could increase exposure of your brand and aid in more consistently achieved full-houses. Further your brand name – The Rose Theatre – is certainly internationally marketable. Home/local productions appear to attract your largest audiences. Careful analysis is needed to identify the ideal balance of productions you stage: would designing your annual program around a majority of such local performances ensure optimum audience numbers, and hence sustainable and predictable margins? Within this analysis it must be noted that the auditorium at The Rose is exceptionally well-equipped and this factor should also aid in attracting â€Å"big name† producers, actors and performers – should more marketing resources be directed at attracting draw card â€Å"names† and hence a wider-ranging audience? Finally but perhaps most importantly, the upgrading of the facilities at the theatre, peripheral to the performance hall, must receive priority. The foyer, the ticket sales lobby, and the faà §ade must aid in raising the profile of the theatre. A strategy to source funding for such improvements is required as many of the proposals in this letter would have their implementation enhanced by a more traditional and inviting â€Å"complete† theatre experience at your venue. Hence a summary of three suggestions each of which will help to enable the ultimate priority: planning the correct balance of productions staged both to attract wider audiences; raising the profile of the theatre among national theatre personalities and tourist audiences;

User Interfaces Ic Compiler Computer Science Essay

User Interfaces Ic Compiler Computer Science Essay IC Compiler is the software package from Synopsys for Physical Design of ASIC. It provides necessary tools to complete the back end design of the very deep submicron designs. The inputs to the IC Compiler are: a gate-level netlist which can be from DC Compiler or third-party tools, a detailed floorplan which can be from previous Design Planning through IC Compiler or other third-party tools, timing constraints and other constraints, physical and timing libraries provided by manufacturer, and foundry-process data. IC Compiler generates a GDSII-format file as output ready for tape out of the chip. In addition, it is possible to export a Design Exchange Format (DEF) file of placed netlist data ready for a third-party router. IC Compiler uses a binary Synopsys Milkyway database, which can be used by other Synopsys tools based on Milkyway. [16] 4.2 User Interfaces IC Compiler can be used either with Shell interface (icc_shell) or with Graphical user interface (GUI). Shell interface is the command-line interface, which is used for batch mode, scripts, typing commands, and push-button type of operations. Graphical user interface (GUI) is an advanced graphical analysis and physical editing tool. Certain tasks, such as very accurately displaying the design and providing visual analysis tools, can only performed from the GUI. Also tool command language (Tcl), which is used in many applications in the EDA industry, is available to IC Compiler. Using Tcl, you can write reusable procedures and scripts. The IC Compiler design flow is an easy-to-use, single-pass flow that provides convergent timing closure. Figure 4.1 shows the basic IC Compiler design flow, which is centered around three core commands that perform placement and optimization (place_opt), clock tree synthesis and optimization (clock_opt), and routing and postroute optimization (route_opt). [16] icc1 Figure 4.1 IC Compiler Design Flow [21] For most designs, if the place_opt, clock_opt, and route_opt steps are followed, IC Compiler will provide optimal results. You can use IC Compiler to efficiently perform chip-level design planning, placement, clock tree synthesis and routing on designs with moderate timing and congestion challenges. To further improve the quality of results for your design you can use additional commands and switches for placement, clock tree synthesis, and routing steps that IC Compiler provides. IC Compiler design flow involves execution of following steps: 1. Set up and prepare the libraries and the design data. 2. Perform design planning and power planning. -Design planning is to perform necessary steps to create a floorplan, determine the size of the design, create the boundary and core area, create site rows for the placement of standard cells, set up the I/O pads. -Power planning, is to perform necessary steps to create a power plan to meet the power budget and the target leakage current. 3. Perform placement and optimization. IC Compiler placement and optimization uses enhanced placement and synthesis technologies to generate a legalized placement for leaf cells and an optimized design, which addresses and resolves timing closure issues for the provided design. You can supplement this functionality by optimizing for power, recovering area for placement, minimizing congestion, and minimizing timing and design rule violations. To perform placement and optimization, use the place_opt core command (or from GUI choose Placement menu and then Core Placement and Optimization sub-menu). 4. Perform clock tree synthesis and optimization. To perform the clock tree synthesis and optimization phase, use the command clock_opt (or choose Clock > Core Clock Tree Synthesis and Optimization in the GUI). IC Compiler clock tree synthesis and embedded optimization solve complicated clock tree synthesis problems, such as blockage avoidance and the correlation between preroute and postroute data. Clock tree optimization improves both clock skew and clock insertion delay by performing buffer sizing, buffer relocation, gate sizing, gate relocation, level adjustment, reconfiguration, delay insertion, dummy load insertion, and balancing of interclock delays. 5. Perform routing and postroute optimization. To perform routing and postroute optimization, use the route_opt core command (or choose Route > Core Routing and Optimization in the GUI). As part of routing and postroute optimization, IC Compiler performs global routing, detail routing, track assignment, topological optimization, and engineering change order (ECO) routing. For most designs, the default routing and postroute optimization setup produces optimal results. If necessary, you can supplement this functionality by optimizing routing patterns and reducing crosstalk or by customizing the routing and postroute optimization functions for special needs. 6. Perform chip finishing and design for manufacturing tasks. IC Compiler provides chip finishing and design for manufacturing and yield capabilities that you can apply throughout the various stages of the design flow to address process design issues encountered during chip manufacturing. 7. Save the design. Save your design in the Milkyway format. This format is the internal database format used by IC Compiler to store all the logical and physical information about a design. [16] 4.3 How to Invoke the IC Compiler 1. Log in to the UNIX environment with the user id and password . 2. Start IC Compiler from the UNIX promt: UNIX$ icc_shell The xterm unix prompt turns into the IC Compiler shell command prompt. 3. Start the GUI. icc_shell> start_gui This window can display schematics and logical browsers, among other things, once a design is loaded. 4.4 Preparing the Design IC Compiler uses a Milkyway design library to store design and its associated library information. This section describes how to set up the libraries, create a Milkyway design library, read your design, and save the design in Milkyway format. These steps are explained in the following sections: à ¢Ã¢â€š ¬Ã‚ ¢ Setting Up the Libraries à ¢Ã¢â€š ¬Ã‚ ¢ Setting Up the Power and Ground Nets à ¢Ã¢â€š ¬Ã‚ ¢ Reading the Design à ¢Ã¢â€š ¬Ã‚ ¢ Annotating the Physical Data à ¢Ã¢â€š ¬Ã‚ ¢ Preparing for Timing Analysis and RC Calculation à ¢Ã¢â€š ¬Ã‚ ¢ Saving the Design 4.4.1 Setting Up the Libraries IC Compiler requires both logic libraries and physical libraries. The following sections describe how to set up and validate these libraries. à ¢Ã¢â€š ¬Ã‚ ¢ Setting Up the Logic Libraries: IC Compiler uses logic libraries to provide timing and functionality information for all standard cells. In addition, logic libraries can provide timing information for hard macros, such as RAMs. IC Compiler uses variables to define the logic library settings. In each session, you must define the values for the following variables (either interactively, in the .synopsys_dc.setup file, or by restoring the values saved in the Milkyway design library) so that IC Compiler can access the libraries: à ¢Ã¢â€š ¬Ã‚ ¢ search_path Lists the paths where IC Compiler can locate the logic libraries. à ¢Ã¢â€š ¬Ã‚ ¢ target_library Lists the logic libraries that IC Compiler can use to perform physical optimization. à ¢Ã¢â€š ¬Ã‚ ¢ link_library Lists the logic libraries that IC Compiler can search to resolve references. à ¢Ã¢â€š ¬Ã‚ ¢ Setting Up the Physical Libraries: IC Compiler uses Milkyway reference libraries and technology (.tf) files to provide physical library information. The Milkyway reference libraries contain physical information about the standard cells and macro cells in your technology library. In addition, these reference libraries define the placement unit tile. The technology files provide information such as the names and characteristics (physical and electrical) for each metal layer, which are technology-specific. The physical library information is stored in the Milkyway design library. For each cell, the Milkyway design library contains several views of the cell, which are used for different physical design tasks. If you have not already created a Milkyway library for your design (by using another tool that uses Milkyway), you need to create one by using the IC Compiler tool. If you already have a Milkyway design library, you must open it before working on your design. This section describes how to perform the following tasks: à ¢Ã¢â€š ¬Ã‚ ¢ Create a Milkyway design library To create a Milkyway design library, use the create_mw_lib command (or choose File > Create Library in the GUI). à ¢Ã¢â€š ¬Ã‚ ¢ Open a Milkyway design library To open an existing Milkyway design library, use the open_mw_lib command (or choose File > Open Library in the GUI). à ¢Ã¢â€š ¬Ã‚ ¢ Report on a Milkyway design library To report on the reference libraries attached to the design library, use the -mw_reference_library option. icc_shell>report_mw_lib-mw_reference_library design_library_name To report on the units used in the design library, use the report_units command. icc_shell> report_units à ¢Ã¢â€š ¬Ã‚ ¢ Change the physical library information To change the technology file, use the set_mw_technology_file command (or choose File > Set Technology File in the GUI) to specify the new technology file name and the name of the design library. à ¢Ã¢â€š ¬Ã‚ ¢ Save the physical library information To save the technology or reference control information in a file for later use, use the write_mw_lib_files command (or choose File > Export > Write Library File in the GUI). In a single invocation of the command, you can output only one type of file. To output both a technology file and a reference control file, you must run the command twice. à ¢Ã¢â€š ¬Ã‚ ¢ Verifying Library Consistency: Consistency between the logic library and the physical library is critical to achieving good results. Before you process your design, ensure that your libraries are consistent by running the check_library command. [16] icc_shell> check_library 4.4.2 Setting Up the Power and Ground Nets IC Compiler uses variables to define names for the power and ground nets. In each session, you must define the values for the following variables (either interactively or in the .synopsys_dc.setup file) so that IC Compiler can identify the power and ground nets: à ¢Ã¢â€š ¬Ã‚ ¢ mw_logic0_net By default, IC Compiler VSS as the ground net name. If you are using a different name, you must specify the name by setting the mw_logic0_net variable. à ¢Ã¢â€š ¬Ã‚ ¢ mw_logic1_net By default, IC Compiler uses VDD as the power net name. If you are using a different name, you must specify the name by setting the mw_logic1_net variable. 4.4.3 Reading the Design IC Compiler can read designs in either Milkyway or ASCII (Verilog, DEF, and SDC files) format. à ¢Ã¢â€š ¬Ã‚ ¢ Reading a Design in Milkyway Format à ¢Ã¢â€š ¬Ã‚ ¢ Reading a Design in ASCII Format 4.4.4 Annotating the Physical Data IC Compiler provides several methods of annotating physical data on the design: à ¢Ã¢â€š ¬Ã‚ ¢ Reading the physical data from a DEF file To read a DEF file, use the read_def command (or choose File > Import > Read DEF in the GUI). icc_shell> read_def -allow_physical design_name.def à ¢Ã¢â€š ¬Ã‚ ¢ Reading the physical data from a floorplan file A floorplan file is a file that you previously created by using the write_floorplan command (or by choosing Floorplan > Write Floorplan in the GUI). icc_shell> read_floorplan floorplan_file_name à ¢Ã¢â€š ¬Ã‚ ¢ Copying the physical data from another design To copy physical data from the layout (CEL) view of one design in the current Milkyway design library to another, use the copy_floorplan command (or choose Floorplan > Copy Floorplan in the GUI). [16] icc_shell> copy_floorplan -from design1 4.4.5 Preparing for Timing Analysis and RC Calculation IC Compiler provides RC calculation technology and timing analysis capabilities for both preroute and postroute data. Before you perform RC calculation and timing analysis, you must complete the following tasks: à ¢Ã¢â€š ¬Ã‚ ¢ Set up the TLUPlus files You specify these files by using the set_tlu_plus_files command (or by choosing File > Set TLU+ in the GUI). icc_shell> set_tlu_plus_files -tech2itf_map ./path/map_file_name.map -max_tluplus ./path/worst_settings.tlup -min_tluplus ./path/best_settings.tlup à ¢Ã¢â€š ¬Ã‚ ¢ (Optional) Back-annotate delay or parasitic data To back-annotate the design with delay information provided in a Standard Delay Format (SDF) file, use the read_sdf command (or choose File > Import > Read SDF in the GUI). To remove annotated data from design, use the remove_annotations command. à ¢Ã¢â€š ¬Ã‚ ¢ Set the timing constraints At a minimum, the timing constraints must contain a clock definition for each clock signal, as well as input and output arrival times for each I/O port. This requirement ensures that all signal paths are constrained for timing. To read a timing constraints file, use the read_sdc command (or choose File > Import > Read SDC in the GUI). icc_shell> read_sdc -version 1.7 design_name.sdc à ¢Ã¢â€š ¬Ã‚ ¢ Specify the analysis mode Conditions such as fabrication process, operating temperature, and power supply voltage can vary semiconductor device parameters. You can specify the operating conditions for analysis with the set_operating_conditions command. à ¢Ã¢â€š ¬Ã‚ ¢ (Optional) Set the derating factors If your timing library does not include minimum and maximum timing data, you can perform simultaneous minimum and maximum timing analysis by specifying derating factors for your timing library. Use the set_timing_derate command to specify the derating factors. à ¢Ã¢â€š ¬Ã‚ ¢ Select the delay calculation algorithm By default, IC Compiler uses Elmore delay calculation for both preroute and postroute delay calculations. For postroute delay calculations, you can choose to use Arnoldi delay calculation either for clock nets only or for all nets. Elmore delay calculation is faster, but its results do not always correlate with the PrimeTime and PrimeTime SI results. The Arnoldi calculation is best used for designs with smaller geometries and high resistive nets, but it requires more runtime and memory. [16] 4.4.6 Saving the Design To save the design in Milkyway format, use the save_mw_cel command (or choose File > Save Design in the GUI). [16] CHAPTER 5: Design Planning 5.1 Introduction Design planning in IC Compiler provides basic floorplanning and prototyping capabilities such as dirty-netlist handling, automatic die size exploration, performing various operations with black box modules and cells, fast placement of macros and standard cells, packing macros into arrays, creating and shaping plan groups, in-place optimization, prototype global routing analysis, hierarchical clock planning, performing pin assignment on soft macros and plan groups, performing timing budgeting, converting the hierarchy, and refining the pin assignment. Power network synthesis and power network analysis functions, applied during the feasibility phase of design planning, provide automatic synthesis of local power structures within voltage areas. Power network analysis validates the power synthesis results by performing voltage-drop and electromigration analysis. [16] Figure 5.1 IC Compiler Design Planning [21] 5.2 Tasks to be performed during Design Planning à ¢Ã¢â€š ¬Ã‚ ¢ Initializing the Floorplan à ¢Ã¢â€š ¬Ã‚ ¢ Automating Die Size Exploration à ¢Ã¢â€š ¬Ã‚ ¢ Handling Black Boxes à ¢Ã¢â€š ¬Ã‚ ¢ Performing an Initial Virtual Flat Placement à ¢Ã¢â€š ¬Ã‚ ¢ Creating and Shaping Plan Groups à ¢Ã¢â€š ¬Ã‚ ¢ Performing Power Planning à ¢Ã¢â€š ¬Ã‚ ¢ Performing Prototype Global Routing à ¢Ã¢â€š ¬Ã‚ ¢ Performing Hierarchical Clock Planning à ¢Ã¢â€š ¬Ã‚ ¢ Performing In-Place Optimization à ¢Ã¢â€š ¬Ã‚ ¢ Performing Routing-Based Pin Assignment à ¢Ã¢â€š ¬Ã‚ ¢ Performing RC Extraction à ¢Ã¢â€š ¬Ã‚ ¢ Performing Timing Analysis à ¢Ã¢â€š ¬Ã‚ ¢ Performing Timing Budgeting à ¢Ã¢â€š ¬Ã‚ ¢ Committing the Physical Hierarchy à ¢Ã¢â€š ¬Ã‚ ¢ Refining the Pin Assignment 5.3 Initializing the Floorplan The steps in initializing the floorplan are described below. à ¢Ã¢â€š ¬Ã‚ ¢ Reading the I/O Constraints: To load the top-level I/O pad and pin constraints, use the read_io_constraints command. à ¢Ã¢â€š ¬Ã‚ ¢ Defining the Core and Placing the I/O Pads: To define the core and place the I/O pads and pins, use the initialize_floorplan command. à ¢Ã¢â€š ¬Ã‚ ¢ Creating Rectilinear-Shaped Blocks: Use the initialize_rectilinear_block command to create a floorplan for rectilinear blocks from a fixed set of L, T, U, or cross-shaped templates. These templates are used to determine the cell boundary and shape of the core. To do this, use initialize_rectilinear_block -shape L|T|U|X. à ¢Ã¢â€š ¬Ã‚ ¢ Writing I/O Constraint Information: To write top-level I/O pad or pin constraints, use the write_io_constraints command. Read the Synopsys Design Constraints (SDC) file (read_sdc command) to ensure that all signal paths are constrained for timing. à ¢Ã¢â€š ¬Ã‚ ¢ Adding Cell Rows: To add cell rows, use the add_row command. à ¢Ã¢â€š ¬Ã‚ ¢ Removing Cell Rows: To remove cell rows, use the cut_row command. à ¢Ã¢â€š ¬Ã‚ ¢ Saving the Floorplan Information: To save the floorplan information, use the write_floorplan command. à ¢Ã¢â€š ¬Ã‚ ¢Writing Floorplan Physical Constraints for Design Compiler Topographical Technology: IC Compiler can now write out the floorplan physical constraints for Design Compiler Topographical Technology (DC-T) in Tcl format. The reason for using floorplan physical constraints in the Design Compiler topographical technology mode is to accurately represent the placement area and to improve timing correlation with the post-place-and-route design. The command syntax is: write_physical_constraints -output output_file_name -port_side [16] Figure 5.2 Floor Plan After Initialization [21] 5.4 Automating Die Size Exploration This section describes how to use MinChip technology in IC Compiler to automate the processes exploring and identifying the valid die areas to determine smallest routable, die size for your design while maintaining the relative placement of hard macros, I/O cells, and a power structure that meets voltage drop requirements. The technology is integrated into the Design Planning tool through the estimate_fp_area command. The input is a physically flat Milkyway CEL view. 5.5 Handling Black Boxes Black boxes can be represented in the physical design as either soft or hard macros. A black box macro has a fixed height and width. A black box soft macro sized by area and utilization can be shaped to best fit the floorplan. To handle the black boxes run the following set of commands. set_fp_base_gate estimate_fp_black_boxes flatten_fp_black_boxes create_fp_placement place_fp_pins create_qtm_model qtm_bb set_qtm_technology -lib library_name create_qtm_port -type clock $port report_qtm_model write_qtm_model -format qtm_bb report_timing qtm_bb 5.6 Performing an Initial Virtual Flat Placement The initial virtual flat placement is very fast and is optimized for wire length, congestion, and timing. The way to perform an initial virtual flat placement is described below. à ¢Ã¢â€š ¬Ã‚ ¢ Evaluating Initial Hard Macro Placement: No straightforward criteria exist for evaluating the initial hard macro placement. Measuring the quality of results (QoR) of the hard macro placement can be very subjective and often depends on practical design experience. à ¢Ã¢â€š ¬Ã‚ ¢ Specifying Hard Macro Placement Constraints: Different methods can be use to control the preplacement of hard macros and improve the QoR of the hard macro placement. Creating a User-Defined Array of Hard Macros Setting Floorplan Placement Constraints On Macro Cells Placing a Macro Cell Relative to an Anchor Object Using a Virtual Flat Placement Strategy Enhancing the Behavior of Virtual Flat Placement With the macros_on_edge Switch Creating Macro Blockages for Hard Macros Padding the Hard Macros à ¢Ã¢â€š ¬Ã‚ ¢ Padding the Hard Macros: To avoid placing standard cells too close to macros, which can cause congestion or DRC violations, one can set a user-defined padding distance or keepout margin around the macros. One can set this padding distance on a selected macros cell instance master.During virtual flat placement no other cells will be placed within the specified distance from the macros edges. [16] To set a padding distance (keepout margin) on a selected macros cell instance master, use the set_keepout_margin command. à ¢Ã¢â€š ¬Ã‚ ¢ Placing Hard Macros and Standard Cells: To place the hard macros and standard cells simultaneously, use the create_fp_placement command. à ¢Ã¢â€š ¬Ã‚ ¢ Performing Floorplan Editing: IC Compiler performs the following floorplan editing operations. Creating objects Deleting objects Undoing and redoing edit changes Moving objects Changing the way objects snap to a grid Aligning movable objects 5.7 Creating and Shaping Plan Groups This section describes how to create plan groups for logic modules that need to be physically implemented. Plan groups restrict the placement of cells to a specific region of the core area. This section also describes how to automatically place and shape objects in a design core, add padding around plan group boundaries, and prevent signal leakage and maintain signal integrity by adding modular block shielding to plan groups and soft macros. The following steps are covered for Creating and Shaping Plan Groups. à ¢Ã¢â€š ¬Ã‚ ¢ Creating Plan Groups: To create a plan group, create_plan_groups command. To remove (delete) plan groups from the current design, use the remove_plan_groups command. à ¢Ã¢â€š ¬Ã‚ ¢ Automatically Placing and Shaping Objects In a Design Core: Plan groups are automatically shaped, sized, and placed inside the core area based on the distribution of cells resulting from the initial virtual flat placement. Blocks (plan groups, voltage areas, and soft macros) marked fix remain fixed; the other blocks, whether or not they are inside the core, are subject to being moved or reshaped. To automatically place and shape objects in the design core, shape_fp_blocks command. à ¢Ã¢â€š ¬Ã‚ ¢ Adding Padding to Plan Groups: To prevent congestion or DRC violations, one can add padding around plan group boundaries. Plan group padding sets placement blockages on the internal and external edges of the plan group boundary. Internal padding is equivalent to boundary spacing in the core area. External padding is equivalent to macro padding. To add padding to plan groups, create_fp_plan_group_padding command. To remove both external and internal padding for the plan groups, use the remove_fp_plan_group_padding command. à ¢Ã¢â€š ¬Ã‚ ¢ Adding Block Shielding to Plan Groups or Soft Macros: When two signals are routed parallel to each other, signal leakage can occur between the signals, leading to an unreliable design. One can protect signal integrity by adding modular block shielding to plan groups and soft macros. The shielding consists of metal rectangles that are created around the outside of the soft macro boundary in the top level of the design, and around the inside boundary of the soft macro. To add block shielding for plan groups or soft macros, use the create_fp_block_shielding command. To remove the signal shielding created by modular block shielding, use the remove_fp_block_shielding command. [16] 5.8 Performing Power Planning After completed the design planning process and have a complete floorplan, one can perform power planning, as explained below. à ¢Ã¢â€š ¬Ã‚ ¢ Creating Logical Power and Ground Connections: To define power and ground connections, use the connect_pg_nets command. à ¢Ã¢â€š ¬Ã‚ ¢ Adding Power and Ground Rings: It is necessary to add power and ground rings after doing floorplanning. To add power and ground rings, use the create_rectangular_rings command. à ¢Ã¢â€š ¬Ã‚ ¢ Adding Power and Ground Straps: To add power and ground straps, use the create_power_straps command. à ¢Ã¢â€š ¬Ã‚ ¢ Prerouting Standard Cells: To preroute standard cells, use the preroute_standard_cells command. à ¢Ã¢â€š ¬Ã‚ ¢ Performing Low-Power Planning for Multithreshold-CMOS Designs: One can perform floorplanning for low-power designs by employing power gating. Power gating has the potential to reduce overall power consumption substantially because it reduces leakage power as well as switching power. à ¢Ã¢â€š ¬Ã‚ ¢ Performing Power Network Synthesis: As the design process moves toward creating 65-nm transistors, issues related to power and signal integrity, such as power grid generation, voltage (IR) drop, and electromigration, have become more significant and complex. In addition, this complex technology lengthens the turnaround time needed to identify and fix power and signal integrity problems. By performing power network synthesis one can preview an early power plan that reduces the chances of encountering electromigration and voltage drop problems later in the detailed power routing. To perform the PNS, one can run the set of following commands. [16] synthesize_fp_rail set_fp_rail_constraints set_fp_rail_constraints -set_ring set_fp_block_ring_constraints set_fp_power_pad_constraints set_fp_rail_region_constraints set_fp_rail_voltage_area_constraints set_fp_rail_strategy à ¢Ã¢â€š ¬Ã‚ ¢ Committing the Power Plan: Once the IR drop map meets the IR drop constraints, one can run the commit_fp_rail command to transform the IR drop map into a power plan. à ¢Ã¢â€š ¬Ã‚ ¢ Handling TLUPlus Models in Power Network Synthesis: Power network synthesis supports TLUPlus models. set_fp_rail_strategy -use_tluplus true à ¢Ã¢â€š ¬Ã‚ ¢ Checking Power Network Synthesis Integrity: Initially, when power network synthesis first proposes a power mesh structure, it assumes that the power pins of the mesh are connected to the hard macros and standard cells in the design. It then displays a voltage drop map that one can view to determine if it meets the voltage (IR) drop constraints. After the power mesh is committed, one might discover problem areas in design as a result of automatic or manual cell placement. These areas are referred to as chimney areas and pin connect areas. To Check the PNS Integrity one can run the following set of commands. set_fp_rail_strategy -pns_commit_check_file set_fp_rail_strategy -pns_check_chimney_file set_fp_rail_strategy -pns_check_chimney_file pns_chimney_report set_fp_rail_strategy -pns_check_hor_chimney_layers set_fp_rail_strategy -pns_check_chimney_min_dist set_fp_rail_strategy -pns_check_pad_connection file_name set_fp_rail_strategy -pns_report_pad_connection_limit set_fp_rail_strategy -pns_report_min_pin_width set_fp_rail_strategy -pns_check_hard_macro_connection file_name set_fp_rail_strategy -pns_check_hard_macro_connection_limit set_fp_rail_strategy -pns_report_min_pin_width à ¢Ã¢â€š ¬Ã‚ ¢ Analyzing the Power Network: One perform power network analysis to predict IR drop at different floorplan stages on both complete and incomplete power nets in the design. To perform power network analysis, use the analyze_fp_rail command. To add virtual pads, use the create_fp_virtual_pad command. To ignore the hard macro blockages, use the set_fp_power_plan_constraints command. à ¢Ã¢â€š ¬Ã‚ ¢ Viewing the Analysis Results: When power and rail analysis are complete, one can check for the voltage drop and electromigration violations in the design by using the voltage drop map and the electromigration map. One can save the results of voltage drop and electromigration current density values to the database by saving the CEL view that has just been analyzed. à ¢Ã¢â€š ¬Ã‚ ¢ Reporting Settings for Power Network Synthesis and Power Network Analysis Strategies: To get a report of the current values of the strategies used by power network synthesis and power network analysis by using the report_fp_rail_strategy command. [16] 5.9 Performing Prototype Global Routing One can perform prototype global routing to get an estimate of the routability and congestion of the design. Global routing is done to detect possible congestion hot spots that might exist in the floorplan due to the placement of the hard macros or inadequate channel spacing. To perform global routing, use the route_fp_proto command. 5.10 Performing Hierarchical Clock Planning This section describes how to reduce timing closure iterations by performing hierarchical clock planning on a top-level design during the early stages of the virtual flat flow, after plan groups are created and before the hierarchy is committed. One can perform clock planning on a specified clock net or on all clock nets in the design. à ¢Ã¢â€š ¬Ã‚ ¢ Setting Clock Planning Options: To set clock planning options, use the set_fp_clock_plan_options command. à ¢Ã¢â€š ¬Ã‚ ¢ Performing Clock Planning Operations: To perform clock planning operations, use the compile_fp_clock_plan command. à ¢Ã¢â€š ¬Ã‚ ¢ Generating Clock Tree Reports: To generate clock tree reports, use the report_clock_tree command. à ¢Ã¢â€š ¬Ã‚ ¢ Using Multivoltage Designs in Clock Planning: Clock planning supports multivoltage designs. Designs in multivoltage domains operate at various voltages. Multivoltage domains are connected through level-shifter cells. A level-shifter cell is a special cell that can carry signals across different voltage areas. à ¢Ã¢â€š ¬Ã‚ ¢ Performing Plan Group-Aware Clock Tree Synthesis in Clock Planning: With this feature, clock tree synthesis can generate a clock tree that honors the plan groups while inserting buffers in the tree and prevent new clock buffers from being placed on top of a plan group unless they drive the entire subtree inside that particular plan group. This results in a minimum of clock feedthroughs, which makes the design easier to manage during partitioning and budgeting. [16] 5.11 Performing In-Place Optimization In-place optimization is an iterative process that is based on virtual routing. Three types of optimizations are performed: timing improvement, area recovery, and fixing DRC violations. These optimizations prese

Death Of A Salesman :: essays research papers

“Maybe I did not live as I ought to have done, … but how could that be, when I did everything properly?';   Ã‚  Ã‚  Ã‚  Ã‚  I can hear it now, Willy Loman uttering those words as he flips through the pages of his life. In the play, Death of a Salesman, by Arthur Miller, we witness the deterioration and death of a very well intentioned man. The quote above from Leo Tolstoy’s Ivan Ilych, could not possibly better echo the situation developed in Arthur Miller’s play. The play becomes Willy Loman’s life trial in which he and his family undergo an intense review of their lives. Willy through his confessions searches to find out what went wrong in his life. However, he dies without ever grasping the truth of it all.   Ã‚  Ã‚  Ã‚  Ã‚  Willy Loman is a traveling salesman in his sixties. As we first find him, he is in the beginning of an emotional crisis. His past, recurring to him in realistic flashbacks, is interfering with the present. Each episode draws forth another problem that Willy has to face in his present situation. The problem for Willy was the question that he was asking himself. It is a question that many older individuals ask themselves, “Did I succeed in life, was it all worth it?'; Poor Willy is beginning to realize that he has lived his entire life for the wrong reasons.   Ã‚  Ã‚  Ã‚  Ã‚  Willy raised his two sons in all the wrong ways. He encouraged cheating and mocked hard work and true success. Everything in his life was a false standard. Willy’s view of an individual’s success was how well that individual was, “liked.'; He instilled in his children all the wrong values and encouraged all the wrong things. This poor moral installment is typified in this conversation between Willy and his son Biff.   Ã‚  Ã‚  Ã‚  Ã‚  BIFF: I flunked math dad……. Would you talk to him? He’d like you Pop. You know the way you could talk.   Ã‚  Ã‚  Ã‚  Ã‚  WIILY: You’re on. We’ll drive right back   Ã‚  Ã‚  Ã‚  Ã‚  BIFF: Oh, Dad, good work! I’m sure he’ll change it for you!. See, the reason he hates me, Pop-one day he was late for class so I got up at the blackboard and imitated him. I crossed my eyes and talked with a lithp.   Ã‚  Ã‚  Ã‚  Ã‚  WILLY: laughing: You did? The kids like it? I really found this conversation to show the exact problem that Willy had. He had instilled the worst values in his children and then never sought to correct them.
