Beschreibung
Zusammenfassung:Asymptotic waveform evaluation (AWE), which is based upon moment-matching, has been demonstrated as an efficient approach for CAD circuit simulation/analysis. The authors describe an approach for overcoming the inherent instability associated with AWE and moment-matching methods as they apply to circuit analysis problems. The efficiency and accuracy of this algorithm were demonstrated in the analysis of large, lumped RLC interconnect-circuit analysis problems and printed circuit board interconnections.< >
