    摘要: A method, a computer program, and an apparatus are provided for generating circuit energy models for a macro using multiple clock gating inputs. Circuit energy models are used to estimate system power consumption. The present invention enables circuit energy models to be created for macros that contain multiple clock gating inputs. Energy tables are created based upon the macro's input switching factor and the clock activation percentage. The clock activation percentage is produced by turning on and off the multiple clock gating inputs during the simulations. These energy tables are generated from a minimum number of power simulations. By using clock activation percentage as a parameter accurate power estimations are produced.

    摘要: A method, a computer program, and an apparatus are provided for generating circuit energy models for a macro containing internal clock gating. Circuit energy models are used to estimate system power consumption. The present invention enables circuit energy models to be created for macros that contain internal clock gating and multiple clock gating inputs. To achieve accurate power estimates a voltage supply is connected to each clock activate signal. Energy tables are then created based upon the macro's input switching factor percentage and clock activation percentage. These power tables are generated from a minimum number of power simulations. By incorporating internally generated clock activate signals into the power estimations the macro energy tables are much more accurate.
