Experimental Evaluation of Testability Measures for Test Generation
S.J. Chandra, Janak H. Patel · 1989
This paper presents results of an extensive study of five existing testability measures when used to aid heuristics for automatic test pattern generation algorithms. Each measure was evaluated using over 60 000 faults in circuits of varying size and complexity. The per- formance of these measures was rated using several different criteria. Based on these results the performance of a composite test generation strategy that uses multiple guidance heuristics was evaluated. The re- sults indicate that this strategy not only provides better fault coverage but also reduces the average time taken to generate a test or determine that a given fault is undetectable.
