Abstract:
Some embodiments provide sampling of a data signal output from a path stage using a latch, sampling of the data signal output from the path stage using an edge-triggered flip-flop, comparing a first value output by the latch with a second value output by the edge-triggered flip-flop, and generating an error signal if the first value is different from the second value.
