Abstract
Correct and accurate evaluation as to which portion of a program to be subjected to rate performance evaluation takes much time is disclosed. Program counters (101c, 101d) hold instructions in simulation of a simulation engine (101). An instruction execution count and a cumulative clock cycle count required for the execution are arranged for the same instruction and stored in an execution count storage array (102b) and a cumulative clock cycle count storage array (102c), respectively. The execution count of the same instruction and the cumulative time required for the execution thereof are determined.
