Hi, I'm porting and old MPW-2 design to the gf180 PDK and what ever I try I always get:
Reached 20 congestion iterations with less than 15% of reduction between iterations. Routing congestion too high. Check the congestion heatmap in the GUI.
. I try to increase the size and reduce the density but always get to that point. Any good recommendations to reduce congestion?

please file github issue https://github.com/The-OpenROAD-Project/OpenLane/issues here with
issue_reproducible
also share repo link
r
you can install openroad, use
openroad -gui
and
source ./run.tcl
to re-run route again. Then you can know where the congestion located.
