An Improved AMG-based Method for Fast Power Grid Analysis

The continuing VLSI technology scaling leads to increasingly significant power supply fluctuations, which need to be modeled accurately in circuit design and verification. Meanwhile, the huge size of power grid requires its analysis to be fast and highly scalable. Algebraic multigrid (AMG) has been recognized as a promising approach for fast power grid analysis. We propose several techniques to improve AMG-based power grid analysis: (1) dynamic reduction threshold, (2) weighted interpolation and (3) a new error smoothing
