摘　　要：在理想互连传输矩阵级联模型的基础上,通过引入返回路径不连续的传输矩阵,提出了一种新的模型.把非理想返回路径传输矩阵级联模型分析结果与S参数模型分析结果对比,验证了新模型的准确性,新模型可以准确地得到非理想互连上信号的耦合串扰噪声.最后分析研究了开槽对串扰的影响.仿真结果表明,传输线应紧挨开槽端口布线,并且传输线间距应尽量大.The transmission matrix for return path discontinuity is introduced to the transmission matrix model of ideal interconnect,and a new model is presented.Compared with the S-parameter model,the performance of the new model is verified and the accurate coupling crosstalk noise of non-ideal interconnect can be obtained.Finally,the influence of cutout on crosstalk is also studied.Simulation results show that the transmission lines should be placed close to the edge of cutout and that the space between two lines should be as large as possible.
