Hi Brantley !

 I possess an XSA-3S1000 too, unfortunatley i wasnt able to go so far than compile
the project for this board. Can please help me with the main project files of [i guess ISE 6.x or Sympl] ?

 Would be nice if publish somewhere the project [even in that stage] for this new XSA-3S1000 board,
i think there would be high interest of others, especialy that the the board is really cheap and the XVS800
one board is obsloeted.

 Myself I would love if share it with me.
