ABSTRACT:
A method and circuits for monitoring and detecting an error in the static pervasive signals applied to input/output pins of an integrated circuit during functional operation of the integrated circuit. The method and circuits provide a signal signature of each of one or more groups of the static pervasive signals and then monitoring the signal signature for any change of logic level.
