... in Fig. 2. Figure 2 also shows that the fault f1 (output of c2 stuck-at-1) can explain the failing test response, therefore diagnosis will correlate this with the physical layout of the net driven by c2 as well as its physical neighbors to come up with diagnosis suspects. For example, if this net...
