PROBLEM TO BE SOLVED: To provide a digital/analog mixed simulation capable of detecting a high impedance input from an analog part to a logic part. SOLUTION: A resistor for PULLUP/PULLDOWN is connected to a connection part between the analog part and a digital part, and a function for forcibly setting potential in the connection part in a high impedance time to an intermediate potential is provided. A function for monitoring potential in the connection part is provided, and when the intermediate potential is detected, the high impedance condition can be detected in this digital/analog mixed simulation.
