摘要
从统计概率的角度出发 ,提出一种采用瑞利分布的延迟度量———互连线延迟的瑞利度量 (RLD) 该算法仅需要采用前两个瞬态 ,计算简单 ,而且准确性较好 。
From the point of view of statistical probability, this paper presents a novel and simple delay metric based on the Rayleigh distribution, called RLD (Rayleigh-based Delay). By this metric, only the first two moments are needed to estimate the interconnect delay. The results from RLD and the SPICE simulation results are almost the same, especially for the far-end nodes.
