Design of Self-Testing Checkers for m-out-of-n Codes Using Parallel Counters

This paper extends the design method of self-testing checkers (STCs) for some m-out-of-n (m/n) codes, proposed recently in IEEE Trans. Comput., 1995 by Dimakopoulos et al. The checkers are built using a pair of parallel counters (composed of full-adders and half-adders) with a total of n inputs and a 2-rail STC. We show here how to build this type of checkers for a number of m/n codes for which previous methods failed.
