摘　　要：为了提高多导体传输线的瞬态响应分析效率与时空计算精度,将计算流体力学领域的守恒元与求解元法引入到互连传输线的分析中,根据电报方程的结构特性,建立了多导体传输线瞬态响应模型,推导出了适用于求解电报方程的计算格式。通过算法验证,分析了多导体传输线内部的电压变化特性,并通过仿真结果的对比,验证了引入方法的可靠性与有效性。研究结果表明,上述方法可分析线上任一点的电压、电流波形,串扰特性更加明显,且无须解耦过程,计算格式简单,具有相同的时空精度与较高的稳定性,可应用于包括非均匀传输线、端接非线性负载在内的一般的互连传输线的瞬态分析。To improve the transient analysis efficiency and calculation accuracy of the multi-conductor transmission lines,the CE/SE method which is used in the field of CFD is applied to the interconnect transmission lines analysis.A transient response model is developed by considering the structure characteristic of telegrapher equations.The CE/SE method is devised for solving the telegrapher equations.By algorithm test,the voltage change characteristic of the multi-conductor transmission lines is analyzed and the effectiveness of this method is verified.The results show that the CE/SE method can be used to analyze voltage and current wave at any point on lines and the crosstalk characteristics is more obvious.This method does not require decoupling and has the advantages of simple algorithm,high precision and good stability.This approach can be applied to analyze general interconnect transmission lines including non-uniform transmission lines and lines with nonlinear loads.
