Abstract
In an embodiment, a clocked storage device such as a pulse flop is provided. The pulse flop includes a latch coupled to receive a scan data input to the pulse flop. The latch receives the scan data input during one of the phases of the clock, and retains the received input during the other phase. The other phase is the phase in which the pulse to the pulse flop occurs. Thus, when scan data is captured in the pulse flop, the latch at the next pulse flop in the chain may be closed and may prevent a race condition in propagating the scan data.
