摘要： A power estimation system uses a hardware accelerated simulator to advance simulation to a point of interest for power estimation. The hardware accelerated simulator generates a checkpoint file, which is then used by a software simulator to initiate simulation of the processor design model for power estimation. An on-the-fly power estimator provides power calculations in memory. Thus, the power estimation system described herein isolates instruction sequences to determine portions of software code that may consume excess power or generate noise and to provide a more accurate power estimate on the fly.

摘要： A method, a computer program, and an apparatus are provided for generating circuit energy models for a macro using 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 clock gating inputs. Power tables are created based upon the macro's input switching factor percentage and the clock activation percentage. These power tables are generated from a minimum number of power simulations. By using clock activation percentage as a parameter accurate energy tables are produced.

摘要： A method, an apparatus, and a computer program are provided for predicting power consumption for chip. The model for predicting power consumptions is modified so at to provide a high degree of accuracy with a minimal amount of computing time. Traditionally, when modeling a chip, a vast amount of time and computer resources were required to predict power consumption. Techniques required less time and less computer power, but the accuracy also decreased. However, by breaking down a chip into macros and developing energy rules for each macro, simple techniques can be employed to accurately predict power consumption under real world conditions with a minimal amount of time and computing power.

摘要： The present invention relates generally methods and apparatus for controlling current demand in an integrated circuit. One embodiment relates to a method that includes detecting if a supply voltage overshoot or a undershoot is present or anticipated, and if detected, controlling current consumed by a power consumption circuitry to ensure that the power supply voltage remains within acceptable levels. Other embodiments relate to an integrated circuit having a capacitive decoupling structure, power consumption circuitry, and power consumption control circuitry for controlling current consumed by at least a portion of the power consumption circuitry. Therefore, embodiments of the invention relate to monitoring and controlling power consumption (i.e. current demand) of a power consumption circuit (such as an integrated circuit) in order to prevent devastating supply voltage undershoots, overshoots, and oscillations.

摘要： A method, system, and computer program product are provided for distributing net power accurately. A workload is simulated operating on an integrated circuit. Net switching activity is determined for a set of nets and a set of subnets in the integrated circuit. Net switching data is generated based on the net switching activity. A net power value is calculated for each individual net and each individual subnet using the net switching data and a net capacitance for each individual net or subnet. Each calculated net power value is assigned to one of a set of source devices that drives the individual net or subnet, wherein the net power is distributed accurately. A net power assignment list is generated based on the assigning of each net power value to one of the set of source devices that drives the individual net or subnet.
