ABSTRACT:
A modeling method and a simulation method enable a circuit board to undergo modeling without deterioration of simulation precision while describing with no matrix shape. A circuit simulator analyzes power/ground noise of a circuit board with single current change source. A process regards the circuit board as an aggregate of thin doughnut boards of concentric circle shape with the current change source as the center, subsequently, approximating the aggregate of the doughnut boards to be an aggregate of rectangular boards with respective circumferences of the doughnut boards as widths and respective cut-lengths of the same as lengths, then forming respective transmission line models taking respective rectangular boards of the aggregate of the rectangular boards as the transmission line, thus connecting respective transmission line models in series to make it a simulation model of the circuit board.
