Several techniques have been proposed which mainly resort to logic simulation, reverting to fault simulation only when strictly required. In this paper we present a new Genetic Algorithm-based test generation method which exploits information coming from a logic simulator (e.g., the circuit activity and the reached states) to guide the search process, in particular in the fault excitation phase. Experimental results show the effectiveness of the proposed method when compared with other Genetic Algorithm-based test generators.","PeriodicalId":330767,"journal":{"name":"Proceedings Sixth Asian Test Symposium (ATS'97)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130224047","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}

Then by computer simulations, we investigate the recognition rate in terms of the number of snapping faults and reliabilities of lines and the learning cycle. The results show that our method is more efficient and useful than the method of Tan et al.
