摘要
In a particular embodiment, a method of generating an advanced gating cell clock tree includes determining a timing margin for a path between a clock gating cell and a digital data storage element such as a latch or flip flop. The circuit contains a clock source and when the timing margin for the path meets a predetermined threshold, the clock gating cell is automatically moved closer to the clock source. In a particular embodiment, the timing margin is automatically determined. A clock tree synthesis is performed to insert one or more buffers into the path and create an advanced gating cell clock tree.
