tangxifan	5d79a3f69f	critical bug fixed when annotating the routing results. Add previous node check. This is due to that some loops between SB/CBs may exist when routing congestion is high, which leads to same nets appear in the inputs of a routing multiplexer. Actually one of them is driven by the other as a downstream node Using previous node check can identify which one to pick	2020-06-17 11:17:57 -06:00
tangxifan	2e3a811f4f	critical bug fixed in repacking. This is due to depop50% local routing where the same net may be mapped to two different pins in the same pb_graph_pin. Now we restrict the pin searching. But in long term, we should sync the pb_route results to post routing results	2020-04-18 21:04:46 -06:00
