An optimal test structure is a circuit which allows one to characterize a specified set of circuit parameters as accurately as possible in the presence of measurement noise and other potential errors. The methodology is based upon recently developed statistical techniques for optimal design of experiments; these techniques allow analog systems to be characterized as accurately and efficiently as possible, thereby reducing cost and/or increasing accuracy. The usefulness of the methodology is illustrated with a fabricated circuit. The most interesting result is that relatively complex circuits are frequently more efficient than commonly used simple circuits.","PeriodicalId":424579,"journal":{"name":"Proceedings of 14th VLSI Test Symposium","volume":"293 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126926126","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 method is based on the fact that some input values remain constant when two successive input vectors are applied. For a transition between two input states, the output function is reduced to a function of few variables. An analysis of the reduced function allows one to obtain the delay faults which are detected by the corresponding transition. The analysis allows one to know if a fault is robustly testable or non robustly testable and validatable, or weakly verifiable: in every case the corresponding tests are obtained. An application of the results to random testing of faults allows one to observe that some non robustly testable faults are easier to detect than some robustly testable faults.","PeriodicalId":424579,"journal":{"name":"Proceedings of 14th VLSI Test Symposium","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130444007","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 consequences of such an evolution in the year 1996, is the capability to put several hundred kilobytes of memory on a single microprocessor core with complexities ranging in the 30 million transistors per chip. What is behind such an evolution is clearly two challenges that still have not been met: (a) Designing for such complexities, using system level design methodologies going from the behavioral level down to silicon (that means, software-hardware co-design, advanced floor planning and complex validation approaches). (b) Power conscious design (that means designing with data throughput constraints within the chip and minimizing power consumption with low-voltage, high-speed optimization of the device behavior). Capitalizing on intellectual property in a company will also be of major importance to address the new, emerging markets like multimedia, where experiences from various market segments should be reused in a single system on a chip. The reusability of functions previously designed in heterogeneous technologies will be needed (abstraction from netlist). The economy of system on chip remains to be proven in most of the applications where limited quantities are needed and where programmability may be the only solution to go to.","PeriodicalId":424579,"journal":{"name":"Proceedings of 14th VLSI Test Symposium","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116411571","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 fault coverage of march tests is analysed in a novel way, i.e., in terms of their detection capabilities for: simple faults, and linked faults; whereby the infinite class of linked faults has been reduced to a set of realistic linked faults. Thereafter the paper presents a methodology to design tests for realistic linked faults, resulting in the new tests March LR, March LRD and March LRDD. These new tests will be shown to be more efficient and to offer a higher fault coverage than comparable existing tests.","PeriodicalId":424579,"journal":{"name":"Proceedings of 14th VLSI Test Symposium","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128546186","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}
