However, interactions between dynamic circuit styles and PD-SOI complicate testing. This paper describes the issues of testing domino circuits fabricated in SOI technology and new tests are proposed to address the interactions. A fault modeling analysis is described which demonstrates that the overall fault coverage can be improved beyond that of traditional testing of domino circuits in bulk technology.","PeriodicalId":403864,"journal":{"name":"Proceedings of the Ninth Asian Test Symposium","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116084102","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}

Meanwhile, signal settling time of the tester between two consecutive test items being applied can also be minimized since all test items are connected together into a continuous one. The interconnection problem is transformed to the Rural Chinese Postman (RCP) problem. The RCP problem is a famous NP-hard problem, one way to solve the RCP problem is by modeling as an integer linear programming (ILP) model. However, in the worst case, it will incur an exponential number of constraints; therefore, it is not suitable for practical usage. Instead of putting all constraints at once, we generate and solve a number of successive ILP models with the smaller number of constraints. The total numbers of iterations and constraints applied to solve ILP models are analyzed and compared.","PeriodicalId":403864,"journal":{"name":"Proceedings of the Ninth Asian Test Symposium","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124683581","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}

However, like other scan-based methods, the LFSR based pattern generation schemes take a long test application time on feeding deterministic patterns from the LFSR into a scan chain. In this paper we derive a generalized relationship between the bits in the original scan chain and the states of the LFSR such that the bits generated by an LFSR in any future clock cycle can be pre-generated by the proposed test pattern generator. With this relationship, we can divide a scan chain into multiple sub-chains and use an LFSR-based multiple sequence generator to simultaneously generate all the subsequences required by the sub-chains, hence can greatly reduce the test application time.","PeriodicalId":403864,"journal":{"name":"Proceedings of the Ninth Asian Test Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129789752","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 self-checking properties of semi-modular asynchronous circuits with respect to certain stuck-at faults have been known for many years, but the restrictions have been such that it has not been feasible to make use of this property to enhance testability. In this paper we demonstrate the feasibility of a technique to determine whether a proposed asynchronous circuit implementation is totally self-checking with respect to all output stuck-at-faults. This test can he incorporated into the design process to select a self-checking implementation when several alternatives are available.","PeriodicalId":403864,"journal":{"name":"Proceedings of the Ninth Asian Test Symposium","volume":"1 7759 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116560760","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}

However, due to the low pin-count-to-component-count ratio, the controllability and observability of such circuits decrease significantly. As a result, the testing of such highly complex and dense circuits becomes very difficult and expensive. A testable/fault-tolerant FFT processor is proposed in this paper. We first propose a testable design scheme for FFT butterfly networks based on M-testability conditions. According to the M-testability conditions, a novel design-for-testability approach is presented and applied to the module-level systolic FFT arrays. Our M-testability conditions guarantee 100% single-module-fault testability with a minimum number of test patterns. Based on this testable design, a reconfiguration mechanism is incorporated to bypass the faulty cells and the testable/fault-tolerant structures are constructed. Special cell designs are presented to implement the design-for-testability and reconfiguration mechanisms. The reliability of the FFT system increases significantly and the hardware overhead is low-about 16% for the module-level design.","PeriodicalId":403864,"journal":{"name":"Proceedings of the Ninth Asian Test Symposium","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132945633","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 peak periodicity and the peak width of the power waveforms for scan-based circuits are analyzed. An interleaving scan architecture based on adding delay buffers among the scan chains is proposed which can significantly reduce the peak power. This method can be efficiently employed in a recently proposed broadcast multiple scan architecture due to the sharing of scan patterns. The effects of the interleaving scan technique applied to the conventional multiple scan and the broadcast multiple scan with 10 scan chains are investigated. The improvement percentage can be up to 50% when the data output of a scan cell is affected by the scan path during scan. When the data output is disabled during scan, 76% of peak-power reduction can be achieved.","PeriodicalId":403864,"journal":{"name":"Proceedings of the Ninth Asian Test Symposium","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127856441","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}
