@Matt Liberty @Vijayan Krishnan Hello!! The detail_place.tcl file in ORFS has a block of code where I could see -max_displacement this was passed to improve_placement. As per the Openroad documentation max_displacement is a variable passed to detail_placement. What is improve_placement and what does it do?

check this proc: https://github.com/The-OpenROAD-Project/OpenROAD/blob/32620a14a9c4ae342e1691250405719f5b5bcee4/src/dpo/src/Optdp.tcl

improve_placement takes a legalized placement and tries to move instances around while keeping it legalized and reducing wire length through various methods

Got it 👍
