摘要
PROBLEM TO BE SOLVED: To provide a computing system for accurately analyzing in a short time the fluctuation of power supply voltage in a printed wiring board mounted with a semiconductor integrated circuit and other passive components.;SOLUTION: This power supply voltage fluctuation analysis system comprises a means for generating a power source system wiring model by circuit simulation using an equivalent circuit generated by dividing power source system wiring and a unit current source in a plurality of parts with respect to a power source system wiring area, roughly divided in grid shape, of the semiconductor integrated circuit, and a means for generating an equivalent circuit model of a power source supply system by connecting an LSI model including the power source system wiring model, and a printed wiring board model including the passive components. Model accuracy equivalent to the subdivided case is secured.;COPYRIGHT: (C)2009,JPO&INPIT
