Abstract
A method for determining clock uncertainties is provided. The method includes identifying clock transfer types between registers from an integrated circuit design and identifying contributors to the clock uncertainties for each of the clock transfers. The jitter associated with each identified contributor is calculated for both set-up time and hold time. This calculated jitter is incorporated into a slack calculation to determine whether timing constraints are met for a circuit design.
