After you settle on the organization of your project constraint files, you must
validate the read sequence of the files depending on the content of the files. In
Project Mode, you can modify the constraint file sequence in the
Vivado®
IDE or by using the reorder_files Tcl command. In Non-Project Mode, the sequence is directly
defined by the read_xdc (for XDC files) and source (for constraints generated by Tcl scripts) commands
in your compilation flow Tcl script.
