Every time an assignment statement is executed during performing a simulation according to a second variable memory system, it is determined whether a value interpreted to have the same meaning is assigned to the assignment statement in the simulation according to a first variable memory system and in the simulation according to the second variable memory system. When the value interpreted to have the same meaning is not assigned, the value assigned according to the second variable memory system is overwritten by an expected value, and a report indicating that the assignment statement is a part dependent on a variable memory system is output.
