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?

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