Concurrent fault simulation of MOS digital circuits

Abstract

The concurrent fault simulation technique is widely used to analyse the behavior of digital circuits in the presence of faults. We show how this technique can be applied to metal-oxide-semiconductor (MOS) digital circuits when modeled at the switch-level as a set of charge storage nodes connected by bidirectional transistor switches. The algorithm we present is capable of analysing the behavior of a wide variety of MOS circuit failures, such as stuck-at-zero or stuck-at-one nodes, stuck-open or stuck-closed transistors, or resistive opens or shorts. We have implemented a fault simulator FMOSSIM based on this algorithm. The capabilities and the peformance of this program demonstrate the advantages of combining switch-level and concurrent simulation techniques.
