Unformatted text preview: because only fault-free simulations have to be performed. In deductive fault simulation, a fault list ( L x ) is associated with a signal x . L x is the set of faults that causes x to differ from its fault-free value. Figure 3.26 shows the fault list of each signal with respect to test pattern P 1 . Fault A/ 1 appears in L A because its presence causes the value of primary input A to deviate from its correct value of zero. Fault A/ 0 is not in the fault list because the value of A remains correct when the fault A /0 is present. The fault lists for inputs B and C are derived in the...
