Abstract: Methods for modifying power use of a semiconductor device include receiving, at one or more processors, an activity stream of a simulation of a semiconductor device, the activity stream comprising a stream of signals. Using the one or more processors, integrated circuit actions are recognized from the activity stream, each integrated circuit action representing an abstraction of work done by the semiconductor device. The processor(s) determine one or more values associated with the integrated circuit actions. A model of power use is generated for the semiconductor device, the model based at least in part on the recognized integrated circuit actions and the associated values. Based on an output of the model, power use of the semiconductor device is modified. Other methods and systems related to determining, modeling, and predicting power/energy use of semiconductor devices are also disclosed.

Abstract: A system simulation estimates power consumption based on only the control portion of the input stimuli for the system.

Abstract: A system simulation runs in addition to a standard simulator a power estimation block which uses the instrumented representation of the system and live data from the standard simulator to compute power consumption and then to display this on a GUI.

Abstract: The present invention may comprise an apparatus and method for calculating power consumption, including a unit for generating a clock-level analysis without synthesis of an algorithm description and calculating operating ratios of storage elements and arithmetic units. The invention may also comprise a method for estimating the power to be consumed by a SystemC model. By estimating this value, a user may gauge the amount of power a specific semiconductor design might consume, once manufactured into a chip.

Abstract: This invention describes a high level Application Programming interface to interface with block level verification environments. By using simple tasks such as memory_write, memory_read, reg_write and reg_read, the interface becomes user-friendly, and designers as well as verification engineers may be able to write complex test cases using the present invention. This invention also processes generic data objects, generation methods, and comparison methods which are not coupled to the design under verification. Higher level API and objects need not be re-designed from one application to another when using the present invention.
