DETECTING AND CORRECTING AN ERROR IN A DIGITAL CIRCUIT
Abstract:
A method for detecting and correcting an error in a circuit is provided. The circuit is configured to receive an input signal and clock the input signal with a rising and falling timing signal. The method includes detecting late arrival signal transition of the input signal, at an intermediate point of a path, the path being one through which the input signal transits. The method further includes predicting an error in the input signal in response to detecting the late arrival signal transition at the intermediate point of the path. In addition, the method includes correcting the error in the input signal by manipulating the timing signal and/or a supply voltage.
