ABSTRACT:
A blockage aware zero skew clock routing method for calculating the distance, and therefore the delay, between two points takes into account any blockages along the path between the two points and therefore creates a more usable and realistic measure of delay and allows for minimization, or elimination, of clock skew in the system being designed using the method of the invention.
