PROBLEM TO BE SOLVED: To increase accuracy of performance verification before code generation in model base development for multi-core application.SOLUTION: The performance verification program is executed in a calculation unit to read out a model file including a plurality of task blocks generated by modeling operation of a control program to be executed on a multi-core processor from a storage unit and perform performance verification of the control program. The performance verification program performs: code generation processing for extracting the task blocks from the model file and generating codes for the respective task blocks; actual time calculation processing for calculating the actual time of execution time of the codes in a single core processor for the respective task blocks; and performance verification processing for verifying an execution process of the control program by using the actual time calculated for the respective task blocks.
