It ignore the IO ports when computing wirelength during placement. There is a circular dependency between global placement and io placement. We start the loop in ORFS by ignoring io placement while doing global placement, then do io placement, then re-run global placement considering IOs. Its not perfect but that's the use. @vvbandeira @luarss missing doc |
