Because the Vivado IDE manages your constraints, you must not edit your XDC files at the same time. When the Vivado IDE saves the memory content, the following occurs:

  • The modified constraints replace the original constraints in their original file.
  • The new constraints are appended to the file marked as target.
  • All manual edits in the XDC files are overwritten.
