ABSTRACT:
A logical verification device includes an input unit, a generator, an input constraint information calculator, an output constraint information calculator, an input/output constraint information calculator, a determining unit, and a logic verifying unit. The input unit inputs hardware description information and interface specification description information concerning a communication procedure of a hardware module. The generator generates a finite state machine model concerning a status transition of signals input to and output from the hardware module, based on the interface specification description information. The input constraint information calculator calculates input constraint information using the generated finite state machine model.
