or_gui should load as much data as available

  • or_gui can be used to debug a lot of issues. It may need a little bit of a revamp to support liberty files loading, spef loading, etc.
  • Make or_gui load data depending on the stage of the run.
  • Do not overwrite the files (LEFs for example) by calling the prep command. Or modify prep so it only creates the file if it is not the gui.
  • It is also suffering since people do not even know about its existence. Maybe mention it in the documentation?

I agree. In ORFS we have a set of gui targets that loads the gui with all necessary files from any flow stage.

Flow does not generate the SDF files in sta multi corner. There is no current_sdf that can be loaded from single point. There is no one common "libs" variable, so i have to load .LIB depending on the current stage. Overall there seems there is more work than I expected, therefore I am pausing working on this.

This is handled now by multiple PRs. I believe mainly https://github.com/The-OpenROAD-Project/OpenLane/pull/1244 and https://github.com/The-OpenROAD-Project/OpenLane/pulls?q=is%3Apr+gui
