Abstract

A simulation apparatus includes a generating circuit configured to detect an internal state of a processor at a start of execution of a process block, when among blocks obtained by dividing code of a program executed by the processor that performs out-of-order execution, processing transitions to the process block in a simulation simulating operation in a case where the processor executes the program, the generating circuit being further configured to generate host code that enables calculation of a block execution period for the case where the processor executes the process block, the generating circuit generating the host code by executing the simulation of the process block based on the detected internal state of the processor; and an executing circuit configured to calculate the block execution period by executing the host code generated by the generating circuit.
