In some cases, you might want to use the Vivado IDE to write a constraints file for use in scripted design flows. To export all the constraints applied to the in-memory design to a single constraints file, select File > Export > Export Constraints.

In addition, you can export the I/O standard constraints for I/O ports and banks (both user-specified values and default values assigned by the Vivado IDE) to an XDC file. To export I/O constraints, select File > Export > Export I/O Ports, and generate an XDC file.
