    Termination resistors

      Hello,

         

      I am designing a FX3 board with Spartan 6 FPGA.

         

      My question is: "Do I need 22 Ohm termination resistors on GPIF 2 interface".

         

      I couldn't make a signal integrity simulation since there is no ibis model of the FX3 chip.

         

      The PCB will be very small. FX3 and Spartan 6 will be very close to each other.

         

      Nearly all GPIF pins will be connected to the FPGA.

         

       

         

      Regards,
