Delay testing using automatic test equipment is expensive. Built-in self-test can significantly reduce the cost of comprehensive delay testing by replacing the test equipment. It was found that several multilevel, synthesized, robust path delay testable circuits require impractically long pseudo-random test sequences. Weighted random testing techniques have been developed for robust path delay testing. The proposed technique is successfully applied to these circuits and 100% robust path delay fault coverage obtained using only 1-2 sets of weights.<<ETX>>","PeriodicalId":111088,"journal":{"name":"Proceedings of IEEE VLSI Test Symposium","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124863197","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}

We extend the domain of signal values from the traditional Boolean 0 or 1 value to the real unit interval /spl lsqb/0, 1/spl rsqb/. Responses of Boolean gates comprising the circuit are also extended to deal with real input values. Non-linear smooth functions are constructed for every gate. A non-linear continuous function for the entire circuit is obtained as a summation of the individual gate functions. A similar function is derived for the faulty circuit. We construct an objective function using the good and faulty circuit functions. The objective function is minimized when at least one of the corresponding outputs of the good and faulty circuit differ. The test generation problem is formulated as the minimization of the objective function over a unit hypercube in the Euclidean space. The dimension of the space is equal to the number of primary inputs of the circuit. We optimize the smooth function inside a convex polytope using a variant of gradient descent and line search strategies. We start at the center of the hypercube and follow a trajectory to one of the corners of the hypercube that corresponds to a test vector. Preliminary experimental results on the ISCAS '85 and '89 benchmark circuits demonstrate the feasibility of our approach.<<ETX>>","PeriodicalId":111088,"journal":{"name":"Proceedings of IEEE VLSI Test Symposium","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115908509","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 analyses is made taking into account the bridge resistance value. It is shown that the fault is detectable as a logic error for a given range of bridge resistance values. But, in this range, the logic faulty value is independent of the bridge resistance value. A general electrical model which can be used to determine if a particular structure of transistors gives an intermediate voltage which is higher or lower than a given threshold voltage is proposed. A global procedure to simulate bridging fault is given. By using the proposed equations and model no SPICE simulation is required.<<ETX>>","PeriodicalId":111088,"journal":{"name":"Proceedings of IEEE VLSI Test Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132020573","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 this paper, we address the problem of diagnosing failures in digital filters. It is assumed that the circuit response obtained during off-line testing of digital filters is to be used for fault diagnosis. The tests applied to the filter consist of input data patterns generated by a standard test pattern generation algorithm. We propose a design for diagnosability procedure, based on time space expansion of a digital filter, which allows one circuit node in addition to the normal filter output to be externally observable for diagnosability purposes. The diagnosis is performed by measuring the error magnitudes at the observable circuit nodes at different times during application of the test sequence.<<ETX>>","PeriodicalId":111088,"journal":{"name":"Proceedings of IEEE VLSI Test Symposium","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127250378","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}
