It includes such steps as testability design rule checking and automated repair of identified violations. Potential violations include clock and asynchronous circuitry which do not operate in a manner consistent with the chosen methodology and tools. Repair is performed by transforming the network through the insertion of additional logic to perform test functions (a scan chain, for example) and mapping this logic into the implementation technology, without affecting the original, system mode operation of the network. This paper discusses the concept of test synthesis constraints which embody the conditions under which the circuit must operate in order to be fully testable. Based on the constraints, the circuit is transformed using algorithms similar to those of automatic test pattern generation. Rather than adding entirely new hardware, existing system logic and connectivity is used to implement test functions wherever possible. Results produced by a prototype implementation indicate that test logic can be inserted into a network with very little performance or area overhead.","PeriodicalId":309921,"journal":{"name":"Proceedings., International Test Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116775868","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}

For EST to be effective, testing of a product must achieve a high fault coverage so that as many EST-induced defects can be detected. By utilizing Boundary-Scan (IEEE Std 1149.1-1990), EST can achieve a high fault coverage and at the same time, minimize test cost. The paper describes a complete infrastructure, both software and hardware, for using Boundary-Scan (B-S) in EST. In addition, the paper shows a simplified control mechanism to select individual circuit packs for Boundary-Scan testing. This control mechanism minimizes the number of wires required to drive the control interface and thus, the number of wires in the cable that connects a tester to the backplane of a system under test and across which Boundary-Scan tests are executed. Finally, the paper presents and discusses some study results for evaluating the effectiveness of monitored EST.","PeriodicalId":309921,"journal":{"name":"Proceedings., International Test Conference","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114325533","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}
