A simulation apparatus includes: operations of: dividing code of a program in a target processor into blocks; setting an execution result of an externally-dependant instruction depending on an external environment as a prediction result; carrying out function simulation based on the prediction result; calculating an execution time of the externally-dependant instruction according to instruction execution timing information and a function simulation result; generating host code which makes a host processor execute performance simulation based on the function simulation result: correcting the execution time of the externally-dependant instruction based on a delay time of the externally-dependent instruction and a execution time of an instruction executed before or after the externally-dependent function if an execution result of the externally-dependent function when the host processor executes the host code differs from the prediction result; and setting a corrected execution time of the external-dependent instruction as the execution time of the externally-dependant instruction. |
