7.7 If the pulse is wide and the data arrives while the pulsed latch is transparent, the

latch contributes its D-to-Q delay just like a regular transparent latch. If the pulse is

narrow, the data will have to setup before the earliest skewed falling edge. This is at

time t

- t

+ t

before the latest rising edge of the pulse. After the rising

edge, the latch contributes a clk-to-Q delay. Hence, the total sequencing overhead

is t

+ t

- t

+ t
