Method and apparatus for preparing a simulation model for semiconductor integrated circuit at power supply terminal for simulating electromagnetic interference

摘要

A first variable resistance (2) is connected in series between the internal output terminal (6) and a power terminal (7) and a second variable resistance (3) is connected in series between terminal (6) and a power terminal (8). Variations in resistance of the variable resistances results in variations of currents at the power terminals that are used to estimate the electromagnetic interference from these terminals. Independent claims are included for a method of forming a model for a circuit to simulate electromagnetic interference and for a computer program for forming the model.
