This system provides an integrated layout environment which consists of stick-figure-based graphic editor, a mask artwork generator, a connectivity checker, a circuit parameter extracter and simulator interfaces. All the modules are designed to deal with symbol data, rather than mask artwork, so that fast execution is realized. A method to associate symbol data with actual mask geometry is described along with the data structure employed. Also described is network partitioning by signal names taking into account logical equivalence of transistor circuits.","PeriodicalId":188431,"journal":{"name":"21st Design Automation Conference Proceedings","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129665529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the program has been designed to be generic, the plans are associated with a precast concrete modular housing system. The program development acts as a framework for re-evaluation and modification of an industrialized housing system to include passive or low energy technology. Design criteria are established as objective functions which are linked to analytical programs and files in the database. The program utilizes the record structure of PASCAL to provide its data structure. Data input is interactive using a keyboard or digitizer; output is graphic or numeric.","PeriodicalId":188431,"journal":{"name":"21st Design Automation Conference Proceedings","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130145823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most discussions on this topic have concentrated on the layout of shapes necessary to form the various circuit elements, or connections between user-defined cells. Equally important, but often disregarded, is the necessity to support other design tools in addition to graphics for circuit layout. These include simulators and automatic layout programs that take a description of a circuit at one level and convert it to a lower level. In addition, if cells are part of a library defined and maintained by others, operations must be included to handle the maintenance of generations or versions of a cell design. These aspects of a database management system for engineering design are discussed in light of the tools being developed at the University of Utah and an extended version of System R, developed at the IBM San Jose Research Laboratory. The Utah approach emphasizes the use of previously designed and tested cells, with interconnects at fixed locations, placed on a grid. Because it is unlikely that the designers of circuits designed all (or any) of the cells used in their circuits, special database management operations are necessary to assure that a consistent, working circuit results.","PeriodicalId":188431,"journal":{"name":"21st Design Automation Conference Proceedings","volume":"439 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127603223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
