This new methodology is not based on the prior knowledge of the faulty device resistance. Instead of that, the approach proposes the characterization of the quiescent current by evaluating the minimal power-bus current corresponding to an output voltage range characterized by the designer to be defective. This output voltage is defined by the designer in order to meet some desirable quality requirements for the circuit on the design, for instance, minimum acceptable noise immunity and maximum time delay. For the design of built-in current sensors, these quality requirements define the minimum current resolution. This approach is exemplified with the characterization of an in-house developed cell library.<<ETX>>","PeriodicalId":283218,"journal":{"name":"Digest of Papers Eleventh Annual 1993 IEEE VLSI Test Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133472155","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}

If testability is a concern, these transformations are limited to those that preserve or enhance testability. Such transformations are called testability preserving transformations. The fault model used is pivotal to the analysis of any such transformation. In this paper, the authors chose single-path-propagating hazard-free robust delay fault testability to qualify them. This model was chosen because it disambiguates results of delay testing which are often inconclusive (the presence of a fault can neither be ascertained nor be denied) and ensures stuck-at fault testability as well. Unfortunately, only a few transformations are known to obey testability requirements. This limitation is a serious handicap in attaining other synthesis goals such as area and performance optimization. In this paper the authors establish a relationship between testability properties of logic transformations and their Boolean duals, the application of which enlarges the existing number of testability preserving transforms. They demonstrate further that some of the new transformations thus achieved may actually enhance testability.<<ETX>>","PeriodicalId":283218,"journal":{"name":"Digest of Papers Eleventh Annual 1993 IEEE VLSI Test Symposium","volume":"356 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131605763","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}
