Abstract:Testing and fault-diagnosis of core-based systems are both difficult problems. Being able to identify which module in the core-based system is faulty has become very important. In this paper, we present algorithms to introduce test points for improving the diagnosability of a digital system. We define a measure of diagnosability known as module resolution which relates to the number of circuit modules that are suspected to be faulty after the diagnostic test procedure has been completed. We present a technique… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
