Differential Quadrature Method Based Sensitivity Analysis of Interconnect Lines

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.
