ABSTRACT:
Improved means and methods for detecting the possibility of a failure occurring in the operation of a digital circuit when operating in a normal manner in a data processing system without any previous or present failure having occurred. In a particular preferred embodiment, the potential possibility of a failure occurring in a clocked digital circuit is detected by determining whether an input signal applied to the digital circuit is stable for a predetermined minimum time period relative to the clock.
