Abstract

A method includes: receiving an integrated circuit design including a plurality of sub-circuits and one or more clocks to be distributed to the sub-circuits; setting one or more constraints on generating a clock network for a selected clock of the one or more clocks of the integrated circuit design; building, by a processor, a clock tree graph for the clock network for the selected clock based on a cached initial clock tree graph stored in a memory connected to the processor, the clock tree graph comprising nodes corresponding to the sub-circuits; generating a pin topology for the clock network based on the clock tree graph and the integrated circuit design; and placing, based on the pin topology, one or more pins for the clock network at one or more sides of the sub-circuits within the integrated circuit design to generate a pin placement for the clock network.
