Hi i have looked at the foundation flow scripts.
i didnt found anything regarding floorplanning, should this step exists? or this flow starts from placement step?
Floorplanning is typically an interactive step but if you've scripted your floorplan creation you can specify the script in the setup.tcl file using:
set vars(fp_tcl_file) fileName
The Foundation Flow will then source the script during the init step. Alternatively, if you have it defined in a procedure you can set the variable:
set vars(fp_tcl_proc) procName
Lastly, there are prototyping Foundation Flows you can utilize to do your floorplanning. See the Rapid Adoption Kits available here:
Hope this helps,
