基于微分求积法的互连线灵敏度分析

Differential Quadrature Method Based Sensitivity Analysis of Interconnect Lines

摘要: 提出一种基于微分求积法、对互连线的响应波形进行灵敏度分析的新方法．以传输线时域模型对互连线进行建模，在此基础上导出灵敏度分析模型．由于利用了所有离散点的信息，微分求积法通常只需要较少的采样点就能达到较高的精度．数值算例证明了该方法的有效性．

Abstract: Based on differential quadrature method(DQM),a new method for sensitivity analysis of response waveforms of interconnect lines is proposed.The interconnect line is modeled as the transmission line model in the time domain,from which the model for sensitivity analysis derives.Due to the utilization of information at global grid points,the DQM usually requires fewer sampling points and can reach high accuracy.Numerical examples are presented to demonstrate the validity of the proposed method.
