ELECTRIC CIRCUIT SIMULATION METHOD, AND ANALOG/DIGITAL INTEGRATED SIMULATOR PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a method and program for enabling an electric circuit simulation further close to an actual operation by performing A/D conversion processing and D/A conversion processing following a fluctuation of power source voltage in a simulation of an analog/digital integrated circuit. SOLUTION: When the operation of an electric circuit with an integrated analog circuit and digital circuit is simulated, a threshold for dividing an analog signal to Hi and lo of digital signal in the A/D conversion processing and a voltage value in conversion of Hi of digital signal to analog signal in the D/A conversion processing are dynamically changed according to the value of power source voltage of the analog circuit.
