This paper presents a technique for designing interacting finite state machines which will be totally self-checkingfor any single stuck-at fault. In the proposed technique m-out-of-n codes are used for both primary output andstate assignments. In addition, the next state logic (NSL) for each submachine and the output logic (OL) arerealized such that any single stuck-at fault results in either single bit error or unidirectional multibit error at theoutput. The proposed technique does not have any restriction on the way the NSL and the OL are implemented
