Abstract: According to one implementation of the present disclosure, a method includes: receiving, by a hardware design generation circuit, a plurality of input signals of a software workload on a processing unit; training a power prediction model based on a toggling of the input signals accumulated over a training interval range; determining, by the hardware design generation circuit, a plurality of prediction proxies and respective weightings for the plurality of prediction proxies based at least partially on the trained power prediction model, wherein the plurality of weighted prediction proxies correspond to a power output of the hardware design generation circuit; and generating an updated circuit design of the processing unit based on the power output.
