SIMULATION DEVICE, SIMULATION METHOD, AND COMPUTER READABLE MEDIUM

In a simulation device (100), a calculation section (113) calculates an execution processing time required for executing each instruction code (221) of a plurality of instruction codes. A storage section (140) stores change setting information (230) in which a change rule that changes execution processing times of the plurality of instruction codes included in the processing unit is set. A change section (115) changes the execution processing time into a changed processing time according to the change rule being set in the change setting information (230). The change section (115) also includes the changed processing time of each instruction code of the plurality of instruction codes, in an entire time point (240). A simulation execution section (116) executes a simulation of a target program (210) using the entire time point (240). A monitoring section (120) monitors a status of a target model during execution of the simulation.
