Abstract
Systems and methods of utilizing a hardware state data logger to debug in silicon. One or more hardware state data loggers are incorporated into a circuit design and fabricated along with the functional units of the circuit into a fabricated chip. When a problem is encountered during testing of the fabricated chip, a hardware state data logger is enabled to capture and store with a final sequence of events that led to the error. The stored data is then extracted from the fabricated chip and used to determine the underlying cause of the failure.
