Instrumenting low power coverage counters in emulation

A method of hardware emulation on a computer, the method comprising:

• receiving, by the computer, a hardware description language file and a low power intent file;
• compiling, by the computer, the hardware description language file and the low power intent file into an emulation image;
• loading, by the computer, the emulation image into an emulator;
• executing, by the computer, the emulation image under a test environment including using a plurality of coverage counters configured for low power coverage, the emulator image comprising a coverage counter instantiated for each of a plurality of low power constructs defined in the low power intent file, wherein the coverage counter is width-adjustable;
• modifying, by the computer, during execution of the emulation image at runtime, an execution setup, based on values of the coverage counters in a feedback loop;
• generating, by the computer, a report file comprising a set of low power coverage metrics based on the plurality of coverage counters;
• and
• presenting, by the computer, the report file to a user via a user interface containing at least one of:
• a web-based real-time display of historical and aggregate data, and a waveform view of coverage data and waveforms of design components.
