Hi! 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 Are you placing the macros manually or attempting to auto place them?

@User: Placing them manually.

Maybe add more space between the macros?

Cool I'll try that.
@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

@User Thumb rule is whenever you're facing some issue you need to report to respective repo. Example here is while using OpenLane flow facing some issue, report to OpenLane repo, you will get some quick response
@User set following variable in
config.tcl
and try
set ::env(PL_BASIC_PLACEMENT) 1
