current status is that it gets stuck in 2_1_floorplan, specifically in the resizer. The resizer slowly churns through 233k hold violations

After adding "export REMOVE_ABC_BUFFERS=1", I'm able to get past the initialize floorplan step. The failure now is in the resizer call from CTS. It's encountering 226k hold violations and gets through 129k of them before it hits the max buffer count:

@maliberty, FYI

233k hold violations means that something is not right with the constraints, or CTS got seriously messed up somehow.
