摘要

考虑工艺随机扰动对互连线传输性能的影响

建立了互连线随机扰动模型

提出了一种基于谱域随机方法的互连线串扰分析新方法.该方法将具有随机扰动的耦合互连线模型在线元分析阶段进行解耦

分别采用随机伽辽金方法(SGM)和随机点匹配方法(SCM)进行串扰分析.最后

利用复逼近给出工艺随机扰动下互连线串扰噪声的解析表达式.实验结果表明本文方法不仅可以对工艺随机扰动下的非均匀耦合互连线串扰进行有效估计

相较于SPICE仿真还具有更高的计算效率.

Abstract

The process variations have an impact on the analysis of interconnects.Considering the impact

the model with process variation is proposed and a spectral stochastic method based analysis method for interconnect crosstalk is presented.Coupled interconnects with process variations are decoupled when analyzing the interconnect segments.Then the crosstalk is analyzed by Stochastic Galerkin Method(SGM)and Stochastic Collocation Method(SCM)respectively.Finally

the expression of crosstalk noise is obtained by complex approximation method.Experimental results demonstrate that the proposed analysis method not only evaluates the crosstalk noise of non-uniform coupled interconnects effectively but also shows good computational efficiency
