Clock reconvergence

WebTherefore this "Reconvergence" of the "Clock" paths creates some "Pessimism" that needs to be "Removed" - this is "Clock Reconvergence Pessimism Removal (CRPR)". The difference in how these components were timed in the two paths has to be "added back" to the budget for the path. This is what the "clock pessimism" line is for - it is adding back ... http://www.gstitt.ece.ufl.edu/courses/spring11/eel4712/lectures/metastability/6544743.pdf

WebClock domain crossover paths are false paths for timing tools; any logic in this path must be carefully crafted and verified, because the logic can cause glitches and create functional … WebFeb 21, 2024 · Clock Reconvergence Pessimism, or CRP, is the difference in delay along the common part of the launching and capturing clock paths. It assumes the shared segment has a min delay for one path and a max delay for the other. This is an undesired effect due to the limitation of STA tool. The removal of this pessimism is called CRPR.
