UNIVERSAL TSC MODULE AND ITS APPLICATION TO THE DESIGN OF TSC CIRCUITS

In this paper, we present a universal totally self-checking (TSC) modu le and show that it can be used as a TSC AND, OR, NAND or NOR gate by performing appropriate routing at its input and/or output. We use the two-rail code to encode the signals and consider the multiple unidirec tional stuck-at-fault model. We study the utility of such TSC modules in obtaining the TSC realization of a given circuit fi-om its gate lev el description. We show that it is possible to obtain the SFS realizat ion of a given circuit by replacing each gate in it with its respectiv e TSC version. We discuss the properties that a circuit must have in o rder to obtain its TSC realization in this manner using the TSC gate. Copyright (C) 1996 Elsevier Science Ltd.
