Abstract
Systems and methods for power analysis of a hardware device design. In various examples, a target circuit can be defined within the hardware device design. The target circuit can include a plurality of digital circuit elements linking a plurality of input nodes with a plurality of output nodes. A solver can be used to search for a transition pattern that, when applied to the input nodes, causes a number of output nodes equal to a counter to transition from a first binary value to a second binary value. If a transition pattern cannot be found, the counter is decremented and a new transition pattern is searched for. Once a transition pattern is found, it is determined whether the transition pattern satisfies a constraint.
