Process variation has become a significant concern for static timing analysis. In this paper,
we present a new method for path-based statistical timing analysis. We first propose a
method for modeling inter-and intra-die device length variations. Based on this model, we
then present an efficient method for computing the total path delay probability distribution
using a combination of device length enumeration for inter-die variation and an analytical
approach for intra-die variation. We also propose a simple and effective model of spatial …
