FENCE GROUP

[hemingxiao-3]

Xplace does not seem to support fences and groups.
If I want to do a placement with fence and group constraints, how should I use Xplace?

We haven't yet supported the fence region.

If you want to try fence regions in Xplace, you can handle them using multiple-density systems.

For example, treat the main die and the various fence regions as different density systems.

hi ,
i have meet same issue as follows:

Xplace3/Xplace/src/database.py", line 660, in compute_filler_with_fence
raise NotImplementedError("We haven't yet supported fence region.")

how to avoid this error, if place do not honor the fence region?

another question: if use fence, how to handle them using multiple-density systems?
