Abstract:
A generation apparatus and the like for generating a test vector set capable of reducing differences in a logic value generated before and after a scan capture for outputs from scan cells included in a full-scan sequential circuit are provided. A generation apparatus 200 generating an initial test vector set 216 for a logic circuit includes a target vector identification unit 204 identifying a test vector satisfying a predetermined criterion and to be selected for the number of bits (the number of bit transitions) whose logic values differ before and after scan capture with respect to outputs from scan cells included in the sequential circuit, from among test vectors in the initial test vector set 216, and a test vector set conversion unit 206 converting the test vector identified by the test vector identification unit 204 and to be selected so as to reduce the number of bit transitions with respect to outputs from the scan cells included in the sequential circuit.
