ABSTRACT:
In a logic simulation method for performing logic simulation of a logic circuit including a circuit with unknown internal logic, the circuit itself with the unknown internal logic is used. The internal status of the circuit is set at an objective status using the interrupt operation afforded by the circuit and thereafter, input signal value is applied to the circuit to obtain a resultant output. For other logic circuits without unknown internal logic, software logic simulation is performed. During such software logic simulation, the actual circuit with unknown internal logic is called.
