摘要:
A method for converting globally clock-gated circuits to locally clock-gated circuits is disclosed. A timing analysis is initially performed on an integrated circuit (IC) design to generate a slack time report for all globally clock-gated circuits within the IC design. Based on their respective slack time indicated in the slack time report, all globally clock-gated circuits that should be connected to locally generated clocks are identified. After disconnecting from a global clock tree, each of the identified globally clock-gated circuits is subsequently connected to a locally generated clock having a clock delay comparable to its slack time indicated in the slack time report.
