Abstract
A verification apparatus which verifies whether or not a finite state machine indicating the operation of a synchronous sequential machine satisfies the property indicating the functional specification repeats the image computation in the M and the computation of a set product by q starting with the state set p when the finite state machine M, the subset q of the state of the M, and the subset p of the q are given; and checks the relation of the state set of the computation process. As a result, it can be determined, starting with a certain state in the p, whether or not a state transition path which eternally does not exceed the q exists.
