Banking::chooseCandidateFF() [incremental cluster] #61

Open coherent17 opened 3 months ago

coherent17 commented 3 months ago

bottom up banking and try to update slack for the neighbor cells in resultFFs:

ex: 1 + 1 -> 2 + 2 -> 4 + 4 ->8 |update timing here, update timing for result FFs if you merge some ff.

nowFF chosing order? gather other ff to nowFF choose nowFF as small positive slack to let other to cluster can we consider the bin density @ banking stage?

Hi, image Here getTimingSlack("D") should be change if you want to cluster MBFF -> MBFF (2+2 -> 4) Because for multi bit the pin should be Di, i = 0 ... M
