A modeling technique for current analysis of LSI power port on a printed circuit board is described. The model consists of two parts ; switching circuits and non-switching circuits. The switching circuits are obtained by extracting clock circuits from the full net list and by replacing equivalent circuits with primitive circuits so as to reduce the number of primitive circuits. Then, every primitive circuit is replaced with four SPICE transistors and loading capacitors. The non-switching circuits are obtained from the remaining circuits by extracting the decoupling capacitor between VDD and VSS. With the use of a 32 bit micro controller LSI, power supply current spectrums obtained by a simulation from this model were compared with values measured by magnetic probe method, and good agreement was observed below 400MHz.
