Abstract

To predict the difficulty of testing a wire stuck-atfault, testability analysis algorithms provide an estimatedtestability value by computing controllabilityand observability. In all previous work, signal correlationbetween controllability and observability is generallyignored. As a result, the estimated value can beinaccurate. This paper discusses an efficient method totake into account signal correlation for testabilityanalysis. Our experimental results have shown that,with little run time overhead, significant improvementof testability analysis can be achieved.
