Physical optimization is an optional step of the flow. It performs timing-driven optimization on the negative-slack paths of a design. Optimizations involve replication, retiming, hold fixing, and placement improvement. Because physical optimization automatically performs all necessary netlist and placement changes, place_design is not required after phys_opt_design.
