Abstract
Circuits, systems, and methods are described herein for increasing a hold time of a master-slave flip-flop. A flip-flop includes circuitry configured to receive a scan input signal and generate a delayed scan input signal; a master latch configured to receive a data signal and the delayed scan input signal; and a slave latch coupled to the master latch, the master latch selectively providing one of the data signal or the delayed scan input signal to the slave latch based on a scan enable signal received by the master latch.
