Abstract
An operation verification system and an operation verification device include a computer having installed therein a simulator which simulates a circuit. A control unit which controls an FPGA by a computer includes an operation instruction unit for operating the circuit and the simulator, and a comparison unit which compares a node value of the FPGA when the circuit is operated, obtained from an external memory in which the node value is written from an internal RAM via a bus circuit, and an internal state value corresponding to the node value, to verify operation of the FPGA. The operation instruction unit operates the circuit and the simulator at the same time.
