Abstract
A set of respective first delay values for paths from a clock source to nodes of the integrated circuit is generated. Respective second delay values for the paths are generated from the clock source through the clock tree to the nodes. Each first delay value corresponds to one of the second delay values for one of the nodes, and each is greater than the corresponding second delay value. A set of common delay values is generated, with each common delay value being a delay for a shared portion of the paths from the clock source through the clock tree to two of the nodes. The determined clock skew is based on the first delay value for a first node, the second delay value for a second node, and the common delay value for the shared portion of the paths from the clock source to the first and second nodes.
