Since this problem turns out to be NP-complete, suboptimal solutions can be derived using some heuristics. An algorithm is presented to compute the corresponding weights of the patterns, which are time-dependent in some cases. The entire approach is validated with the help of examples. Only 10-40% of the flip-flops have to be integrated into a partial scan path or into a built-in self-test register to obtain nearly complete fault coverage by weighted random patterns.eninfo:eu-repo/semantics/openAccessFlip-Flop , Selbsttest , Testbarkeit621.3The design of random-testable sequential circuitsconferenceObject2012-08-20
