In contrast to the state-of-the-art approaches the necessary test pattern sequences are generated using the logic function of the circuit to be tested. This enables the usage of both conventional scan flipflops and boundary scan cells, instead of enlarged area-consuming scannable flipflops. Additionally, the test application time can be distinctly reduced since only one test pattern of each test pair has to be loaded into the scan register. Experimental results of the ISCAS-89 benchmark circuits illustrate the efficiency of this new approach.<<ETX>>","PeriodicalId":244297,"journal":{"name":"Proceedings of European Design and Test Conference EDAC-ETC-EUROASIC","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131493730","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}

(1991). The sizing is performed in two levels. At the module level, a leaf cell is chosen based on a height slack (usable area) and timing slack. At the cell level, the cell is sized based on a width constraint imposed from the module level. The problem of sizing a cell is formulated as a nonlinear program. The objective is to minimize the difference of actual arrival time and the required time of all output nodes simultaneously. A benchmarking process has been conducted at both cell level and module level. Experiments on a set of cells show that on the average over 25% performance improvement is obtained by using 0.06% more area. Moreover, for a leaf cell with multiple outputs, the sizer can indeed simultaneously make the arrival time of all output nodes close to the required time. Results of a module level experiment show that using height slack the maximum delay of the circuit can be reduced up to 17.7% without area penalty for the example shown.<<ETX>>","PeriodicalId":244297,"journal":{"name":"Proceedings of European Design and Test Conference EDAC-ETC-EUROASIC","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122375466","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 number of faults has a strong influence on the costs which must be paid for in the generation of a test set. For logical fault models this number can be reduced using equivalence relations between faults. Since the complexity of digital circuits is increasing, hierarchical design is becoming more and more important. In this paper, we show that in the case of a hierarchical circuit description often more equivalence relations between faults can be recognized efficiently than in the case of a nonhierarchical description. With respect to the stuck-at fault model, our experiments show that the computation of these equivalence relations can be performed in negligible time and that the number of faults can be reduced considerably.<<ETX>>","PeriodicalId":244297,"journal":{"name":"Proceedings of European Design and Test Conference EDAC-ETC-EUROASIC","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126466130","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}
