Hi, I'm trying to understand how the OpenLane flow works, so I'm following it from start to finish while documenting my findings along the way. I'm up to

floorplanning

, and I notice that it runs

floorplan.tcl

twice. What's the purpose of that? It looks like the first invocation adds

-save "to=$::env(floorplan_tmpfiles),name=initial_fp,def,sdc,odb"

, does that generate files that are used by the second invocation?

I've never noticed it to run twice. How do you observe this?

It's in the output logs. The actual lines that run it are https://github.com/The-OpenROAD-Project/OpenLane/blob/master/scripts/tcl_commands/floorplan.tcl#L47-L52

That's mysterious to me. @donn do you know why floorplan.tcl is run twice?

@Sean Cross Please raise as GH issue in https://github.com/The-OpenROAD-Project/OpenLane/issues

Alright, I created an issue asking why: https://github.com/The-OpenROAD-Project/OpenLane/issues/1513
