PROBLEM TO BE SOLVED: To eliminate a failure after product mass-selling by issuing an alarm to a user in the case that a second instruction group is executed before a first instruction is executed. SOLUTION: It is detected that an instruction A is not executed before executing an instruction group B and instruction omission on a program is automatically discovered. That is, a target MCU 11 reads and executes a user program stored in an emulation memory 12. At this point, an instruction A comparator circuit 13 and an instruction group B comparator circuit 14 respectively detect that the target MCU 11 executes the instruction A and the instruction group B, and when the instruction A comparator circuit 13 and the instruction group B comparator circuit 14 respectively detect the instruction A and the instruction group B, detection signals 13a and the detection signals 14a are outputted. In such a manner, in the case that the second instruction group B is executed before the first instruction A is instructed, the alarm is issued to the user. |
