Abstract
An interference analysis device that analyzes interference includes an input unit that inputs design data, a selection unit that selects an analysis region, a division unit that divides a wire into segments, a calculation unit that calculates a circuit matrix regarding a coupled line, and an analysis unit that obtains a degree of electromagnetic interference, wherein the calculation unit calculates a circuit matrix of the coupled line, using a parameter set obtained by adding an asymmetry parameter to RLGC parameters of a transmission line in the coupled line. Thus, a method for analyzing an interference of circuit wiring can be provided, which is capable of shortening a processing time substantially while maintaining high precision.
