假设总线和其他信号线在深亚微米超大规模集成电路的电容耦合两，三和无限线系统的延迟，斜率和串扰噪声幅度的简单而有用的解析公式推导。利用推导的公式计算的结果与SPICE模拟结果进行了广泛的比较，证明了解析表达式的有效性。研究了两种模式;从相反方向驱动相邻行的情况和从相同方向驱动相邻行的情况。这些情况对应于VLSI设计中的典型情况，包括噪声幅度和延迟方面的最坏情况。本文还研究了用N阶/π/-梯形RC集总电路近似分布RC线时的延迟误差。
Simple yet useful analytical formulas for delay, slope and crosstalk noise amplitude for capacitively coupled two-, three- and infinite-line systems are derived assuming bus lines and other signal lines in deep-submicron VLSI's. The calculated results using the derived formulas are extensively compared with SPICE simulation results to demonstrate the validity of the analytical expressions. Two modes have been studied; the case where adjacent lines are driven from the opposite direction and the case where adjacent lines are driven from the same direction. These cases correspond to the typical situations in VLSI designs and include worst cases in terms of noise amplitude and delay. Delay error in approximating the distributed RC lines by N-step /spl pi/-ladder RC lumped circuit is also investigated.
