# Pin assignments for the Virtex chip on the XSV Board 1.0
#
# To use the pin constraints in this ucf file with your
# project in the Foundation Project Manager:
#	* Ensure that the ports in your top-level entity use
#	  the same names as those used in this ucf file.
#	* Make a copy of this ucf file and only modify the copy.
#	* In the copy of this file, uncomment the lines containing
#	  pins that your top-level file uses (remove the # from
#	  the start of the lines you wish to uncomment).
#	* If you have not yet implemented your project, run the
#	  implementation, but stop the implementation flow after
#	  the "Translate" step.
#	* In Foundation Project Manager, click on the 
#	  "Implementation" menu and select "Set Constraints File(s)...".
#	* Tick the box labelled "Copy Constraints Data From:".
#	* From the drop down menu select "Custom".
#	* In the dialog box that appears, click "Browse..." and locate
#	  your copy of this file. Then click "Open".
