ContributorThe significance of a global clock lies primarily in its dedicated routing resources, especially for clock signals with large fan-out. Routing these signals through the global clock ensures that, during the layout and routing process, the wire lengths for the clock signals reaching various registers are approximately equal. This, to a certain extent, helps reduce the differences in clock skew.
New ContributorThank you for your response.
I'm more interested on the impact of the literal rise time of a single clock, as opposed to it's skew vs other clocks.
Is there any documentation that discusses the rise time of signals?
And/or what portion of the timing budget it might eat into?
Apologies if this is basic, my background is hardware and I'm relatively new to firmware.
