PURPOSE:To efficiently execute the evaluation and examination of a circuit to be tested with high accuracy by cooperatively operating a dual port random access memory and a processing circuit based on a signal from a simulator main body and executing dummy arithmetic operation. CONSTITUTION:A dual port random access memory 20 and a processing circuit 15a of a controller 66 are cooperatively operated based on the signal from the simulator main body and the dummy arithmetic operation can be executed. Accordingly, even when the dummy arithmetic operation is under execution and one input / output port of the dual port random access memory 20 is in use, the stored contents of the dual port random access memory 20 can be read from the other input / output port. Thus, the read stored contents of the dual port random access memory 20 can be compared with the signal from the simulator main body in a homogeneous dimension and the controller, which is the circuit to be tested, can be efficiently evaluated and examined with the high accuracy. |
