There are a number of different steps. Can you narrow it down?
PSM is doing a matrix solve and that will not be linear in design area. The matrix size will be linear in design area. Smarter gridding would help some. You...
Yes I see the psm has quite a bit of inefficiency in building the matrix, not just solving it. That can be improved.
@gadfort has offered to work on psm (he has similar issues and more concerns)
@AcKoucher have you looked at this?
Are all the blocks hard except 20 in blue? Is the context a mix of hard and soft?
@oharboe can you test the full flow with the latest? That macro placement doesn't look great but perhaps it can go through.
@AcKoucher do you have a sense of why it is so compressed to one corner?
Your placement doesn't appear to match @AcKoucher result. Neither looks great though.
We should wait for https://github.com/The-OpenROAD-Project/OpenROAD/pull/3896 to finish
