Abstract
Signal value storage circuitry 2 includes transparent storage circuitry 4, transition detector circuitry 6 and error detecting circuitry 8. The transition detector circuitry serves to generate a detection pulse when a signal transition is detected at a signal node NS within the transparent storage circuitry. The error detecting circuitry generates an error indicating signal when this detection pulse overlaps in time with the non-transparent phase of a pulse clock signal controlling the signal valve storage circuitry for at least an overlap period TOV.
