本文介绍应用PEEC模型提取VLSI电路中3-D互连寄生电感电阻中出现的多右端线性方程组求解问题.在种子投影多右端方程求解方法EGCR
[5]
的基础上
本文提出一种改进的EGCR方法MEGCR
达到有控制地扩大搜索空间以减少所需正交化时间的目的.它显著加快了多右端方程组的求解速度
在可比精度下
右端数约为30时
综合运用多右端技术及多极加速的本文方法比先进的FastHenry
[1]
快数十倍.
We discuss the problems of solving linear systems with multiple right-hand sides while using PEEC model to extract 3-D parasitic interconnect inductance and resistance in VLSI circuits.Based on the seed projection method EGCR (Extended Generalized Conjugate Residual)
[5]
we propose a modified method MEGCR to simplify the computation of orthogonal procedure through limitedly enlarging the search space of non-seed right-hand sides.It accelerates the speed of solving systems with right-hand sides.Summarizing the technique of solving linear systems with multiple right-hand sides and multipole acceleration
our program runs faster than FastHenry
[1]
tens' times with comparable accuracy when the number of right-hand sides is about 30.
