    We introduce the use of majority voting circuits for increasing yield, reliability, and life cycle of VLSI processor arrays while reducing the overall area and manufacturing cost of the resultant defect and fault tolerant device. Usually, for a redundant fault tolerance, one redundant processing element is used for every faulty processing element. In our method, the majority voting circuits are us... View full abstract»

    The cost of test is an important issue and one which continues to attract a lot of attention even though it is often not fully understood. Most industry designers do not have enough time to devote to an economic analysis of testing options, but it is quite clear that the benefits of doing so are enormous-ultimately very large sums of money can be saved through the use of 'appropriate' test.

    In this paper, a singular pencil (SP) model-based fault diagnosis strategy is developed from the viewpoint of practical control application. The diagnosis scheme is based on a SP model of a lumber drying process, which reveals nonlinear and time-variant behavior due to unmeasurable and measurable disturbance. The fault or failure in the drying process is difficult to detect and diagnosis due to co... View full abstract»

    In spite of good intentions, and the work of many people over many years, test engineers and design engineers are still divided by a great chasm. Design information is still thrown "over the wall" to test, and information from test is seldom reflected back in design. The authors present a systems framework that allows models to be used as design rule specifications in the design process, used as t... View full abstract»
