Additional Context
Please help me how to resolve this error ?
Run make floorplan_issue and attach the test case.
Screenshot won't help to fix the issue.
floorplan is not able to execute because there is no command present in top level makefile of my design
The screen shots suggest he is using openfasoc. @msaligane is there a way to package an issue from fasoc?
Looking at the density it's extremely sparse at 0.8%, maybe that is contributing to the issue
You need to find a way to produce a standalone test case. Without one nothing can be done. I don't use fasoc so I have no idea how to do so with those scripts.
Hi all, I see a similar issue here: https://github.com/The-OpenROAD-Project/OpenROAD/issues/1296
@Eyantra698Sumanto #1296 was closed a long time ago. How is that related?
@maliberty The above screenshot and the #1296 both show the "RePlace diverged at the initial iteration" hence I was wondering.
FYI while I think the fix in the PR is wrong, the test case in https://github.com/The-OpenROAD-Project/OpenROAD/pull/2370 still reproduces. In that case the issue is explained in: https://github.com/The-OpenROAD-Project/OpenROAD/pull/2370#issuecomment-1294796770

@maliberty we do not have that yet. Maybe something to add @lulu9312
@msaligane Correct we don't have this generator yet. @VanshikaTanwar In second screenshot, for your config.mk file I see PLACE_DENSITY is commented. Maybe you should try uncommenting it. Also to run the make floorplan_issue command you need to go to flow/ directory.
@lulu9312 Sir, I already tried uncommenting that PLACE_DENSITY and assigned different values to it but still the same error persist .
Ok sir I will run the make floorplan_issue and then share the SS /file of it what it generates after this command .
