Unformatted text preview: b. What characteristics can be said for f considering that it is aborted by a simulation-based ATPG? c. Suppose a hybrid ATPG detects f ; what synergy is explored to detect f ? 4.31 (Path-Delay ATPG) Consider the circuit fragment shown in Figure 4.62. a b c d e f g h i j ± FIGURE 4.62 Example circuit. a. Generate all paths in this circuit. How many paths are there in this circuit? b. Which paths are functionally unsensitizable? c. For those sensitizable paths, which ones are robustly testable, and which ones are nonrobustly testable? 4.32 (Path-Delay ATPG) Given a combinational circuit with the knowledge of the implication a = 1 → b = 1. How can this knowledge be used to deduce certain paths are unsensitizable?...
