Critical patch on repacking about wire LUT support.

2020-04-19 16:42:31 -06:00
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
