I want to understand core_utilization, but If I fix core_utilization, there is automatic die_area and core_area. What mechanism is in core_utilization command?(config.mk) #C0161A4A59V #C016H8WJMBR The openroad document said “core_area = design_area / (utilization / 100)” but I don’t know where design_area is set up.

Are you referring this: https://github.com/The-OpenROAD-Project/OpenROAD/tree/master/src/ifp#readme
