A totally self-checking checker for Borden's code

It is well known that a large number of errors in VLSI circuits are unidirectional in nature. J.M. Borden (Inf. Control, vol.53, p.66-73, April 1982) has studied a code for detecting only t, not all, unidirectional errors. For a code to be utilized in a self-checking system, a self-checking checker must exist for it. The totally self-checking (TSC) checker is one such checker. Many designs for TSC checkers exist for m-out-of-n codes. However, no work has been reported on the design of a TSC checker for Borden's code. The author presents such a design. They believe that this design may lead to greater applicability of Borden's code to self-checking systems.<
