Abstract
A code converter 11 of a simulation apparatus 1 detects, during the execution of a program in a target CPU, an externally dependent instruction affected by the external environment in each of divided blocks, predicts the execution result of the externally dependent instruction, simulates the instruction execution in the predicted result, and generates a host code in which a code for performance simulation is embedded based on the simulation result. A simulation executor 12 performs performance simulation about instruction execution in the prediction result of the program using the host code, and when the execution result of the externally dependent instruction is different from the setting of the prediction result during the execution, corrects the execution time of the instruction in the prediction result using the execution time of instructions executed before and after the instruction, and the like. A simulation information collector 13 collects and outputs performance simulation information.
