As delay testing using external testers requires expensive ATE, built-in self test (BIST) is an alternative technique that can significantly reduce the test cost. It has been proven that Single Input Change (SIC) test sequences are more effective than classical Multiple Input Change (MIC) test sequences when a high robust delay fault coverage is targeted. It has also been shown that random SIC (RSIC) test sequences achieve a higher fault coverage than random MIC (RMIC) test sequences when both robust and non robust tests are under consideration; the experimental results were based on a software generation of RSIC sequences that are easily generated. Obviously, a hardware RSIC generation providing similar results can be obtained. However, this hardware generator must be carefully designed. In this paper, it is explained what are the criteria which must be satisfied for this purpose. A solution is proposed and illustrated with an example. Then,it is shown that a bad result may be obtained if one of these criteria is not satisfied.","PeriodicalId":339694,"journal":{"name":"IEEE European Test Workshop, 2001.","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121237009","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}

One solution to this problem is to use high-level models in the fault simulation. However, the high-level model used in fault simulations has diferent requirements as compared to the high-level model normally used in IC design. This is because the behaviour of the faulty block is unknown and it is possible that it works totally diflerent from the fault-ffee one. In this paper, a new general structure of a high-level model with three stages is proposed. The approach has been applied to the RECEIVER block of an industrial chip. The fault simulations with this high-level model have been carried out with Dotss, an industrial analogue fault simulation and test optimisation tool based on defect-oriented testing. The results show that this kind of high-level models can work properly in fault simulations and effectively reduce the fault-simulation time.","PeriodicalId":339694,"journal":{"name":"IEEE European Test Workshop, 2001.","volume":"13 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116476325","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}

A high-level fault model called the coupling fault (CF) model is presented which aims to cover both functional and timing faults in an integrated manner. Intuitively, a (single) CF denoted xi|zj exists between input xi and output zj of a module if xi|zj blocks any dynamic effect of xi on zj The set of test vectors CTSxi|zj that detect xi|zj is represented by the boolean difference of zj with respect to xi. A pair of adjacent vectors in CTSxi|zj, constitutes a coupling delay test. This article studies the basic properties of coupling faults and test sets, focusing on the relationship between coupling tests and other high-level tests. A coupling test set provides powerjhl, realization-independent coverage of stuck-at faults. Coupling delay tests can detect all robust path delay faults in any realization of afunction.","PeriodicalId":339694,"journal":{"name":"IEEE European Test Workshop, 2001.","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121792635","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}

VT allows debugging digital and mixed-signal test programs in a simulation environment if a fast and sufficiently accurate IC model can be made available. Behavioural model of the chips under test turned out to be a very promising approach to cover both the needs of designer for the sign-off simulation on chip level and of test engineers for VT.
