Abstract
For fault models with large numbers of faults, such as bridging faults, fault collapsing based on dominance relations can be effective in reducing the test generation time by reducing the number of target faults. When dominance relations are used for fault collapsing, a fault f j is excluded from the set of target faults F if it dominates a fault f i in F. However, if f i remains undetected after test generation, f j may remain undetected as well. We define safe fault collapsing to address this issue. For safe fault collapsing with a parameter s, f j is excluded from the set of target faults F only if f j dominates at least s faults f i1, f i2 , hellip ,f is in F. In this way, if any of the s faults dominated by f j is detected, f j will be detected as well. A higher value of s increases the likelihood of detecting f j without targeting it. We describe a procedure for computing safe collapsed fault sets, and present experimental results of test generation for four-way bridging faults.
