Further Comments on 'Detection of Faults in Programmable Logic Arrays' by J.E. Smith
January 1990 (vol. 39 no. 1)
pp. 155-156

In recent correspondence, L. Ye-Wei and J. Wei have shown two counterexamples that contradict theorems four and five of a paper by J.E. Smith. In his reply, Smith stated an additional condition under which the theorems hold good. The commenters provide a counterexample that contradicts Smith's modified theorem five. They provide another counterexample that contradicts theorem three of Smith's original paper. In his reply, Smith corrects an error in his treatment.
