A high-level test synthesis (HLTS) method targeted for delay-fault testability is presented in this paper. The proposed method, when combined with hierarchical test-pattern generation for embedded modules, guarantees a 100% delay test coverage for detectable faults in modules. A study on the delay testability problem in behavior level shows that low delay-fault coverage is usually attributed to the fact that a two-pattern test for delay testing cannot be delivered to modules under test in two… CONTINUE READING
