Abstract
A method and an apparatus to perform statistical static timing analysis have been disclosed. In one embodiment, the method includes performing statistical analysis on performance data of a circuit from a plurality of libraries at two or more process corners using a static timing analysis module, and estimating performance of the circuit at a predetermined confidence level based on results of the statistical analysis during an automated design flow of the circuit without using libraries at the predetermined confidence level.
