Physical constraints are used to control floorplan, specific placement, I/O assignments, routers and similar functions. Make sure that each pin has an I/O location and standard specified. Physical constraints are covered in the following user guides:
- For locking placement and routing, including relative placement of macros, see the Vivado Design Suite User Guide: Using Constraints (UG903).
- For floorplanning, see the Vivado Design Suite User Guide: Design Analysis and Closure Techniques (UG906).
- For configuration, see the Vivado Design Suite User Guide: Programming and Debugging (UG908).
