How does this affect the runtime?

[maliberty]

This fails in uW:

13:29:50  [INFO GRT-0018] Total wirelength: 11589619 um
13:29:50  [INFO GRT-0014] Routed nets: 89816
13:29:50  [ERROR GRT-0116] Global routing finished with congestion. Check the congestion regions in the DRC Viewer.

@maliberty The runtime of microwatt was largely decreased, taking less than 3 hours to complete when running in my local machine. I don't get why it fails with congestion in the ci, but I'll investigate better.
