Pt clock skew
http://mtv.ece.ucsb.edu/courses/ece156A_14/lecture09.pdf Clock skew (sometimes called timing skew) is a phenomenon in synchronous digital circuit systems (such as computer systems) in which the same sourced clock signal arrives at different components at different times due to gate or, in more advanced semiconductor technology, wire signal propagation delay. The instantaneous difference between the readings of any two clocks is called their skew.

WebJan 3, 2024 · In this book, the term “clock skew” refers to skew caused by spatial constraints. Clock jitter is a measure of how imperfect a clock period is. One way to think about jitter is this: Visualize using an oscilloscope on a clock, setting it to trigger at a rising edge. Then turn the knob of the scope and view a point in time, say, several ... WebIf the input ports are synchronous to external clock, the paths can be constrained for setup as, input_delay + comb_delay (max) < clock delay path (clock skew) + T (clock period of clock) – setup time of latch FF . And For the hold constraints as . input_delay + comb_delay (min) > hold time of latch FF + clock delay path (clock skew).

Clock Skew is the delay difference between the source (SRC) clock path and the destination (DST) clock path. The rough calculation is Clock Skew = DST clock delay - SRC clock delay.
