Abstract
In an approach for processing a circuit design by a programmed processor, a placed circuit design that has been placed on programmable resources of a programmable integrated circuit (IC) is input. A critical path is determined from a first sequential element to a second sequential element assigned to the placed circuit design. A first clock buffer that provides a clock signal to the first and second sequential elements is determined, and an unused clock buffer is selected based on proximity to the first sequential element. The circuit design is modified to include the unused clock buffer as a second clock buffer coupled to receive a clock signal in parallel with the first clock buffer and to provide a clock signal to the first sequential element.
