Database used for interference analysis apparatus for circuit wiring, interference analyzer and interference analysis program, asymmetric coupled-line model

摘要

The interference analysis apparatus for analyzing interference includes an input unit 2 for inputting design data, a selection unit 3 for selecting an analysis region, a division unit 5 for dividing a wiring into segments, and a calculation unit 6 for calculating a circuit matrix for a coupled line. And an analysis unit 7 for determining the degree of electromagnetic interference, and the calculation unit 6 uses a set of parameters obtained by adding an asymmetry degree parameter to the RLGC parameter of the transmission line in the coupled line, and the circuit matrix of the coupled line. Is calculated. Accordingly, it is possible to provide a circuit wiring interference analysis method capable of significantly reducing the processing time while maintaining high accuracy.
