In order to speed up the test points selection method based on cost minimization, and reflecting random pattern testability, we introduce three techniques, the simultaneous selection of plural test points, the simplified selection of test points by the cost reduction factor, and the reduction of the number of test point candidates. We implement a program based on the proposed method and evaluate its efficiency experimentally using large scale circuits (26 k-420 k gates).","PeriodicalId":330767,"journal":{"name":"Proceedings Sixth Asian Test Symposium (ATS'97)","volume":"24 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":"124284411","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}

In the work, we have found that three tests are enough to locate single link fault and four tests are sufficient to detect single sorting element fault in an odd-even sorting network. For location tests for sorting element faults, the numbers of tests depend on the type of faults occurring at the sorting element. For most types of sorting element faults, the numbers are less than four specific tests. For the other types of faults, we have presented the test generation procedure and binary search procedures to generate the tests. The numbers of location tests are less than (n+log/sub 2/n), where n=log/sub 2/N and N is the number of inputs of the sorting network.","PeriodicalId":330767,"journal":{"name":"Proceedings Sixth Asian Test Symposium (ATS'97)","volume":"76 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":"127447849","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}

This paper follows the latter approach, and presents a new method to the automated generation of an initialization sequence for synchronous sequential circuits. We propose a Genetic Algorithm providing a sequence that aims at initializing the highest number of flip flops with the lowest number of vectors. The experimental results show that the approach is feasible to be applied even to the largest benchmark circuits and that it compares well to other known approaches in terms of initialized flip flops and sequence length. Finally, this paper shows how the initialization sequences can be fruitfully exploited by simplifying the ATPG process.","PeriodicalId":330767,"journal":{"name":"Proceedings Sixth Asian Test Symposium (ATS'97)","volume":"19 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":"121822113","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}

The techniques allow the number of test cycles required to be reduced by up to 45% of that achieved using regular dynamic compaction techniques alone, and by up to 98% over that achieved using a single serial scan chain methodology. In addition, the techniques are suitable for both synchronous and asynchronous circuits.","PeriodicalId":330767,"journal":{"name":"Proceedings Sixth Asian Test Symposium (ATS'97)","volume":"122 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":"122749702","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}

The time at which the MD test activates the latest transition at the primary output changes linearly with the size of the target delay. (1) The MD tests determine at a given clock rate (observation time) whether a circuit tender test is marginal chip or not. (2) The MD tests determine the maximum circuit clock speeds. (3) The MD test detects the target gate delay fault regardless of the size of the fault by comparing the latest transition time at the primary output of the fault-free circuit and that of the faulty circuit. In order to determine the detectable size of gate delay faults the proposed method introduces a new extended timed calculus which calculates both the latest transition time at the line in the fault-free circuit and the transition time at the same line affected by a gate delay fault of maximum fault size. We also demonstrate experimental results for gate delay faults on ISCAS benchmark circuits to show the performance of our method.","PeriodicalId":330767,"journal":{"name":"Proceedings Sixth Asian Test Symposium (ATS'97)","volume":"46 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":"124133156","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}
