Abstract
Techniques for an IC design include placing latches between a source and one or more sinks in the IC design, and performing an iterative process for maximizing slack on one or more input nets and one or more output nets for each of the latches, minimizing an absolute difference of the slack. The IC design includes optimizing routing for the latches and placing a clock gating latch in the IC design designated to control a LCB of LCBs. The IC design includes placing LCB logic in the IC design to control a required number of the LCBs, and placing a local clock buffer controller in the IC design in proximity to the positions of the latches.
