Abstract(in Japanese) (See Japanese page)
Abstract(in English) A technique to simulate high frequency current on power and ground planes of printed circuit boards(PCB's) due to high speed switching of LSI's has been developed. The electromagnetic characteristics of multilayered and complicated shaped PCB patterns are modeled using coupled simulation between finite element current distribution calculation and circuit calculation. The technique is applied to power-bus-decoupling method. The result of simulation agrees with measurement with average 1.2dB difference (maximum difference is 4.0dB).
