False-Aggressors-Aware True Crosstalk Noise Analysis with Logic Correlations for Accurate Timing Analysis

摘要

Coupled line switching can contribute to a large portion of the delay as well as the functionality of a circuit. In order to fix a crosstalk noise in noise analysis, it is necessary an additional design cost. Therefore, aggressor nodes that cannot affect victim node have to pruning. In this paper, we present an efficient false aggressor pruning algorithm with functional correlation. Path sensitization algorithm and logic implication approach that use functional information to identify false coupling interaction between coupled lines. Our experimental results show an average of 5.4% aggressor pruning and 14.6% delay reduction due to pruning.
