Abstract
An integrated circuit includes a first circuit and a power meter coupled to the first circuit at selected proxy locations. The power meter includes circuitry for generating toggle data, such as signal transitions or signal levels, from signals at the proxy locations and combiner circuitry for combining the toggle data in a first time window with a set of weight value to produce a measure of power usage in the first circuit. The proxy locations and weight values are selected automatically based on simulated or emulated signals from a larger set of locations in the first circuit and associated power usage in the first circuit.
