摘要
给出了一个求解片上多层互连线的复数传播常数的谱域分析法(SDA).由于SDA是一种全波分析法,其计算量通常很大,为了提高积分方程的求解速度,引入了一个新颖的钟形窗口函数.该函数在谱域内具有低通滤波特性,并且拥有简单闭合的计算公式,能够有效地降低计算复杂度.基于该窗口函数的特性研究,推导出了一个新的用于提高SDA积分求解速度的加速算法.实验证明,该算法具有较高的精度和速度.
Spectral domain analysis（SDA） is presented for solving complex propagation constant of on-chip multi-layer interconnects.As SDA is a full wave solution and is usually computational expensive,a novel bell-shaped window function is introduced to speed up the integral equation（IE）.This novel bell-shaped window function has low-pass-filter feature in the spectral domain.Also it has simple closed-form formula which favorites the computational complexity.Based on this window′s special feature research,a new accelerating algorithm is derived to speed up the SDA integration.Both the accuracy and the speed of the proposed algorithm are proved to be very promising.
