CIRCUIT WIRING INTERFERENCE ANALYSIS DEVICE, INTERFERENCE ANALYSIS PROGRAM, DATABASE USED IN INTERFERENCE ANALYSIS DEVICE, AND ASYMMETRICALLY CONNECTED LINE MODEL |
摘要 |
<p>An interference analysis device that analyzes interference includes an input unit 2 that inputs design data, a selection unit 3 that selects an analysis region, a division unit 5 that divides a wire into segments, a calculation unit 6 that calculates a circuit matrix regarding a coupled line, and an analysis unit 7 that obtains a degree of electromagnetic interference, wherein the calculation unit 6 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.</p> |
