Abstract
An integrated circuit including a degradation monitoring circuit. The degradation monitoring circuit includes a comparison circuit having a delay element including an input coupled to a data node of a timing path and having an output to provide a delayed signal of a data signal of the data node. The comparison circuit includes a logic comparator that provides a logic comparison between a data signal of the data node and the output of the delay element. The monitoring circuit includes a sampling circuit that provides a sampled signal of the output of the logic comparator that is a sampled with respect to a clock signal of the clock signal line. The monitoring circuit includes a hold circuit that provides a signal indicative of a data signal of the data node transitioning within a predetermined time of an edge transition of a clock signal of the clock signal line.
