The basic idea of the method has been obtained from an observation that only an error generated on one of the fault-nets propagates often to the primary outputs under a given test though more than one fault-net exist in the circuit under test. In this method, the fault-nets are located through a repetition of deducing candidates for each individual fault-net under the assumption of single fault-net and ascertaining which is the real one by probing. Probing internal nets is done only for finding the real fault-nets from these candidates. Consequently, it becomes possible to greatly decrease the number of probed nets. Preliminary experimental results show that fault locations are almost completely identified by probing 20% of the nets at most.<<ETX>>","PeriodicalId":208029,"journal":{"name":"Proceedings First Asian Test Symposium (ATS `92)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126960734","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}

All combinational irredundant crosspoint faults in the PLA implementing the combinational component of the machine are testable. The machines produced have short machine-independent justification sequences for each state. The maximum length of these sequences is nv. A unit length sequence verifies that the machine has been actually placed in the reset state after the application of the reset input. The authors have developed an algorithm which does not use fault simulation. Combinational fault simulation is introduced in order to reduce the number of test vectors needed. There is an area overhead associated to the increment in testability. These area penalties have been shown to be smaller for larger machines. The scheme reduces the area overhead of similar approaches previously reported.<<ETX>>","PeriodicalId":208029,"journal":{"name":"Proceedings First Asian Test Symposium (ATS `92)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126557856","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}
