Recursive Algorithm for the Time Domain Macromodel of Interconnects in MCM

提出一种求解高速ＭＣＭ 中有耗互连线两端瞬态响应递归形式的时域宏模型，利用频域内的泰勒近似，通过逆拉氏变换得到一组时域内的递归公式，递归公式只涉及传输线两端的电流和电压，因而具有较高的计算效率，数值实验结果表明，本方法可以达到相当高的精度。

A recursive algorithm of the time domain macromodel is presented for the transient simulation of interconnect systems in the high speed MCM.The Taylor approximation is employed in the frequency domain,then a set of recursive formulas is derived by the inverse Laplace transform.The algorithm comcerns only the quantities at two ends of the lines,so it consumes less computer time and less memory in comparison with other methods.Applications show that the method gives high accuracy.
