摘　　要：基于6节点耦合互连串扰噪声电路模型,提出了一种新的考虑工艺波动的统计互连串扰噪声分析方法,在给定互连参数波动范围条件下,推导出了耦合互连统计串扰噪声的均值和标准差的解析表达式.实验结果表明,与在互连工艺波动研究中广泛采用的蒙特卡罗方法相比,新方法在确保计算精度的前提下大大缩短了计算时间,且采用新方法计算得到的RC互连串扰噪声均值误差低于2.36%,而标准差误差则低于7.23%.Based on the six-node template circuit of coupling interconnects, a novel method for analyzing the statistical crosstalk noise of RC interconnects with process variations is proposed. Analytical expressions for mean and standard deviation of the statistical crosstalk noise are derived {or a given fluctuation range of interconnect parameters. Simulation results show that the time of calculation is greatly shortened with a good calculating precision using the proposed statistical model as compared to the widely used Monte Carlo method. Calculated results also indicate that the errors of the mean and standard deviation are less than 2.36 % and 7.23 % respectively.
