Abstract
A communication protocol validation system which produces a state transition expansion chart having a plurality of states and a plurality of transitions between states in electrical form to find errors such as an unspecified executable transition, a specified unexecutable transition and a deadlock has been improved by providing new error items of a bounded overflow and an unbounded overflow and deleting redundant transitions. Thus, a number of states and a number of transitions in the chart are reduced, and the validation is implemented by using a reasonable amount of hardware in a reasonable time.
