Abstract :
This paper describes a method of identifying a set of crosstalk-induced delay faults which may need to be tested in synchronous sequential circuits. In this process, the false crosstalk-induced delay faults that need not (and/or can not) be tested in synchronous sequential circuits are also identify. Our method classifies the pairs of aggressor and victim lines, using topological information and timing information, to deduce a set of faults that need to be tested in a sequential circuit. Experimental results for ISCAS´89 benchmark circuits show that the lists of the target faults obtained by the proposed method are sufficiently smaller than the sets of all possible combinations of faults
