Abstract

Abstract—Beerel [1] showed that semimodular asynchronous circuits are totally self-checking with respect to multiple output stuck-at faults that are nonexitory and nonsubstitutional. We show that, in circuits with atomic gate implementations, it is possible to ensure that all exitory multiple output stuck-at faults will cause the circuit to halt.
