A new gate delay model for simultaneous switching and its applications

Abstract

We present a new model to capture the delay phenomena associated with simultaneous to-controlling transitions. The proposed delay model accurately captures the effect of the targeted delay phenomena over a wide range of transition times and skews. It also captures the effects of more variables than table lookup methods can handle. The model helps improve the accuracy of static timing analysis, incremental timing refinement, and timing-based ATPG.
