Is there a reason the

GLB_RT_ALLOW_CONGESTION

variable only affects the script on

or_groute.tcl

but not on

or_resizer_routing_timing.tcl

?

[ERROR GRT-0118] Routing congestion too high.
Error: or_resizer_routing_timing.tcl, 41 GRT-0118

That seems like a mistake. Please file an issue (or a PR)

I checked and that issue was already solved two weeks ago on the

The-OpenROAD-Project/OpenLane

The

efabless/OpenLane

mpw-3a that I'm using doesn't have that change yet
