SABLE accepts information about the nesting and interconnectivity of components, and combines it with descriptions of their behavior, which are written in a new language called ADLIB (A Design Language for Indicating Behavior). ADLIB allows users to define the \"data level\" at which each component operates, and to specify mechanisms for translating information between these levels. The facilities provided by SABLE are general and flexible, making it feasible to simulate a large system at several levels of abstraction simultaneously. Examples are included that illustrate: the' use of ADLIB for behavior specification, techniques for data level translations, and a design methodology that makes use of multi-level simulation.","PeriodicalId":345241,"journal":{"name":"16th Design Automation Conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127229668","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}

The use of traditional computer animation techniques allows for more efficient analysis of time dependent data, and advanced interactive methods of storing and retrieving spatial data offers help in displaying and evaluating the objects being designed. The system is planned to interface with an existing computer-aided design project that emphasizes the structural analysis phase of the design process. The fundamental goal of the project was to incorporate color graphics into the design system while maintaining a high degree of user interaction. Descriptions are included of the operating system environment and the necessary supporting software and hardware components.

Functional and structural masking and covering relations among faults are defined. These relations can be exploited to greatly simplify multiple fault analysis and their test generation.
