Verification apparatus, verification method, and computer-readable recording medium for supporting engineering change order

摘要

A verification apparatus includes a reference circuit-side point extraction unit that extracts a point where the input value of a signal changes due to a logic change in a reference circuit in a state before and after the logic change, based on information regarding a signal that has changed due to the logic change in the reference circuit; a circuit to be verified-side point extraction unit that extracts a point where the input value of a signal changes due to a logic change in a circuit to be verified in a state before and after the logic change, based on information regarding a signal that has changed due to the logic change in the circuit to be verified; and a verification script generation unit that generates a verification script with use of the points extracted by the reference circuit-side point extraction unit and the circuit to be verified-side point extraction unit.
