METHOD APPARATUS AND PROGRAM FOR PREPARING A SIMULATION MODEL FOR SEMICONDUCTOR INTEGRATED CIRCUIT AT POWER SUPPLY TERMINAL FOR SIMULATION ELECTROMAGNATIC INTERFERENCE

摘要

PURPOSE: To provide a generating technology of a semiconductor integrated circuit power supply model for EMI simulation which can be easily and automatically made. CONSTITUTION: In generating a simulation model expressed in a description form by variable resistance and load capacity, such a method is employed that values of the variable resistance and load capacity are obtained based on a change in current waveform flowing between power supply terminals of a semiconductor integrated circuit, and a simulation model can be made extremely easily and accurately.
