Patent abstract
Aspects include parsing, by a computer system, a design file of an integrated circuit including a plurality of stages to extract a plurality of inputs and outputs of a plurality of latches. The computer system can sort the latches based on latch locations in the stages and build a plurality of ordered vectors of signals before and after the latches based on the sorting. The computer system can build a plurality of parity vectors for each of the ordered vectors of signals before and after the latches, build a latch bank for each of the parity vectors before the latches, and build a parity vector comparison to detect a parity failure based on comparing the parity vectors after the latches with an output of the latch bank.
