Abstract

In one embodiment of the invention, a method for designing an integrated circuit is disclosed. The method includes automatically partitioning clock sinks of an integrated circuit design into a plurality of partitions; automatically synthesizing a clock tree from a master clock generator into the plurality of partitions to minimize local clock skew within each of the plurality of partitions; and automatically synthesizing clock de-skew circuitry into each of the plurality of partitions to control clock skew between neighboring partitions.
