04/26/2022, 1:58 AMHi! I am trying to place two macros side-by-side. However, I see that the nesterov solver is not able to successfully place them; it eventually gives us after 2800 iterations with the following error: [ERROR GPL-0305] RePlAce diverged at newStepLength. Any leads on how can I go about fixing this?

@User: I opened the issue in the caravel repo since I was using OpenLane via the caravel_user_project makeflow for my experiment: https://github.com/efabless/caravel_user_project/issues/118
