Still, conventional research results present only average values for the yield. The present paper discloses how the yield shows a beta distribution and how that yield can be evaluated by obtaining its cumulative probability. Furthermore, a method is introduced to calculate the systematic yield that can be obtained with relative ease even with the tester on-line. Finally, concrete examples are given where an improvement in the yield was accomplished through the use of this calculation method.","PeriodicalId":199542,"journal":{"name":"Proceedings of the 11th Asian Test Symposium, 2002.

The first stage selects test points based on an earlier testability measure conflict. A new testability measure conflict+ based on conflict analysis of hard-faults in the process of test generation is introduced, which emulates most general features of sequential ATPG. A new design for testability algorithm is proposed to select test points by using conflict+. Test points are selected in the second stage based on the hard faults after the initial ATPG run of the design for testability circuit in the preliminary stage. Effective approximation schemes are adopted to get reasonable estimation of the testability measure. Several effective techniques are adopted to accelerate the process of the proposed design for testability algorithm.","PeriodicalId":199542,"journal":{"name":"Proceedings of the 11th Asian Test Symposium, 2002.

Additionally, this approach allows estimating the final network reliability. This approach is based on the mutation analysis technique and is used during the training process of the ANN. The basic idea is to train the ANN in the presence of faults (single-fault model is assumed). To do so, a set of faults is injected into the code describing the ANN. This procedure yields mutation versions of the original ANN code, which in turn are used to train the network in an iterative process with the designer until the moment when the ANN is no longer sensible to the single faults injected. In other words, the network became tolerant to the considered set of faults. A practical example where an ANN is used to recognize an electrocardiogram (ECG) and to measure ECG parameters illustrates the proposed methodology.","PeriodicalId":199542,"journal":{"name":"Proceedings of the 11th Asian Test Symposium, 2002.

This paper presents a unified approach to SOC testing that uses a built-in self-test (BIST) technique based on summations of cores' test output voltages (SOCTOV), which has the advantage of small hardware overhead and fast testing time. The proposed BIST technique is developed in conjunction with our previous proposed BIST technique which is based on weighted sums of selected node voltages (WSSNV) for embedded cores. The WSSNV BIST technique provides high fault coverage for individual cores while the SOCTOV BIST technique provides a 100% fault diagnosis resolution for locating the faulty core. It is an alternative solution to SOC testing especially when chip area overhead is a critical concern.","PeriodicalId":199542,"journal":{"name":"Proceedings of the 11th Asian Test Symposium, 2002.

We propose a test scheduling algorithm for BISTed memory cores to minimize the overall testing time under the test power constraint. The proposed algorithm combines several approaches for a near-optimal result, based on the properties of BISTed memory cores. By proper partitioning, an analytic exhaustive search finds optimal results for large memory cores, while a heuristic ordering with simulated annealing further handles a large amount of smaller memory cores. On the average, the results are within 1% difference of the optimal solution for the cases of 200 memory cores.","PeriodicalId":199542,"journal":{"name":"Proceedings of the 11th Asian Test Symposium, 2002.
