A functional verification system which provides information as to whether a signal has reached all possible states. For example, in the case of a signal with 0 and 1 as possible states, a 2 bit variable is initialized to 00. When a value of 1 is received for the signal, the first bit is set to 1 and when a value of 0 is received for the signal, the second bit is set to 1. Accordingly, by examining the two bits, one may determine whether the signal has attained one or both of 0 and 1 states.
