I am getting errors in placement stage using replace in the openlane flow. Attaching the errors:

[INFO] FillerInit: FillerCellArea = -nan

[INFO] FillerInit: FillerCellSize = (-nan, -nan) [ERROR]: during executing: "replace < /openLANE_flow/scripts//replace_gp.tcl |& tee >&@stdout /openLANE_flow/designs/AMUX2_3V_top/runs/19-08_05-37//logs/placement/replace.log" [ERROR]: Last 10 lines: child killed: segmentation violation After debugging found out that the following line in replace_gp.tcl is causing the error: rep place_cell_nesterov_place. can someone help?

If it reproduces every time, upload your input files to GitHub and file a bug report for the tcl script

Or you can break out the debugger and try to figure it out yourself; assuming you don't have that much time then uploading means someone else can do that

Yes I don't think the error is with the whole TCL script. Just the one line. I was trying to debug, but don't know how exactly the place_cell_nesterov_place works.

Hi, if you share your input files, it would help find out what's wrong.
