Asymptotic Waveform Evaluation via a Lanczos Method

In this paper we show that the two-sided Lanczos procedure combined with implicit restarts, offers significant advantages over Pad6 approximations used typically for model reduction in circuit simulation. Keywords-Dynamical systems, Model reduction, Numerical methods, Pad6 approximation, Lanczos algorithm.

Asymptotic waveform evaluation for timing analysis

For digital system designs the propagation delays due to the physical interconnect can have a significant, even dominant, impact on performance. Timing analyzers attempt to capture the effect of the interconnect on the delay with a simplified model, typically an RC tree. For mid-frequency MOS integrated circuits the RC tree methods can predict the delay to within 10 percent of a SPICE simulatio...

Numerical Solution of Diffraction Problems: A High-Order Perturbation of Surfaces and Asymptotic Waveform Evaluation Method

The rapid and robust simulation of linear waves interacting with layered periodic media is a crucial capability in many areas of scientific and engineering interest. High-order perturbation of surfaces (HOPS) algorithms are interfacial methods which recursively estimate scattering quantities via perturbation in the interface shape heights/slopes. For a single incidence wavelength such methods a...
