Abstract: Embodiments of the present technology provide a synchronous device. The synchronous device provides a first latch configured to store a data input signal during a first state of a first clock signal and a slack guard circuit. The slack guard circuit provides a delay element coupled to the first latch and configured to generate a delayed data signal, a gated-input cell coupled to the delay element and configured to propagate the delayed data signal during the first state of the first clock signal, and a comparator coupled to the first latch and the gated-input cell.
