a state matcher for a logic circuit may detect at least one of a buggy state of the logic circuit , a precursor to a buggy state of the logic circuit and a verified state of the logic circuit based on a plurality of signal values indicative of a state of the logic circuit . a recovery controller for a microprocessor may reconfigure the microprocessor to a trusted feature mode in response to receiving a signal indicating that the microprocessor is in a predefined state and operate the microprocessor in the trusted feature mode for a predetermined period of time .
