    The concept of design for diagnosability (DfD) is introduced as a different concept than design for testability (DfT). Separating design for diagnosability guidelines from those of the more general design for testability guidelines enables circuit designers to distinguish between those guidelines that separate good circuits from faulty ones and guidelines that are aimed at improving the repair pro...

    Using Bayes' theorem, the false alarm rate is shown to be a function of the reliability of the monitored functional system, the reliability of the built-in-test (BIT) system, and the coverage by the BIT of the monitored functional system. Partial differentiation of the false alarm rate formula reveals that the false alarm rate varies inversely with BIT reliability, inversely with BIT coverage, and... View full abstract»

    This paper describes an approach for validating XML data that are governed by an ISO 10303-11 EXPRESS schema. The approach relies on transformation from XML to a temporary file in ISO 10303-21 format. The approach does not require tailoring the transformation script to a particular EXPRESS schema, so long as one follows a regular pattern when mapping the EXPRESS schema to XML. The original motivat... View full abstract»
