Sequential n-detection criteria: keep it simple!

The idea of n-detection is to exposure a target fault in n different ways. A major concern about the n-detection has been the question whether different test vectors really do excite the fault in different ways leading to different activation and propagation conditions. A special problem was the lack of methodology for answering this question. Our goal was to develop such a methodology and to evaluate its usefulness. In this work, we use a bridging fault-based non-target fault model for evaluating n-detect sequences.
