Abstract

In this paper, we introduce an efficient analysis method for the power network of general topology. The new approach is based on algebraic multigrid (AMG) method that can avoid the slow convergence of basic iterative methods. An innovative adaptive coarsening scheme is employed to further speed up the performance, taking advantage of the spatial variation of power supply noise. Experimental results show that our method is more than 100 times faster than SPICE3.

基于自适应代数多网格方法的电网分析

本文介绍了一种对一般拓扑的电力网络进行有效分析的方法。该方法基于代数多重网格(AMG)方法，避免了基本迭代方法收敛缓慢的问题。采用一种创新的自适应粗化方案，利用电源噪声的空间变化进一步提高了性能。实验结果表明，我们的方法比SPICE3快100倍以上。
