Industry trends aimed at integrating higher levels of circuit functionality have triggered a proliferation of mixed analog-digital systems. Magnified noise coupling through the common chip substrate has made the design and verification of such systems an increasingly difficult task. In this paper we present a fast eigendecomposition technique that(More)
Accurate modeling of noise coupling effects due to crosstalk via the substrate is an increasingly important concern for the design and verification of mixed analog-digital systems. In this paper we present a technique to accelerate the model computation using BEM methods that can be used for accurate and efficient extraction of sub-strate coupling(More)
The extraction of substrate coupling resistances can be formulated as a first-kind integral equation, which requires only discretization of the two-dimensional contacts. However, the result is a dense matrix problem which is too expensive to store or to factor directly. Instead, we present a novel, multigrid iterative method which converges more rapidly(More)

Abstract: Multipole-accelerated surface-volume methods have proved to be very efficient techniques for delay and cross-talk simulation of three-dimensional integrated circuit interconnect. However, to be efficiently combined with transistor circuitry in a SPICE-level simulation, reduced-order models which have accurate low-frequency behavior must be(More)
— Accurately accounting for three-dimensional (3-D) geometry and distributed RC effects in on-chip interconnect is important for predicting crosstalk in memory cells, analog circuits, and regions of congested routing in digital circuits. In this paper we describe a multipole-accelerated, mixed surface-volume formulation, and a preconditioned model-order(More)
