Complete Fault Detection Tests of Length 2 for Logic Networks under Stuck-at Faults of Gates

详细

We consider the problem of the synthesis of the logic networks implementing Boolean functions of n variables and allowing short complete fault detection tests regarding arbitrary stuck-at faults at the outputs of gates. We prove that there exists a basis consisting of two Boolean functions of at most four variables in which we can implement each Boolean function by a network allowing such a test with length at most 2.
