I need to interface VGA screen to Virtex-5 FPGA board in order to display an image. I know how to interface VGA with Spartan-3E starter board. But I have no idea how to do it with Virtex-5.

  • If the board has a VGA port, you should be able to interface with it in roughly the same way, just with different pin assignments. – Vlad Nov 16 '15 at 17:40
  • This board has DVI port in place of VGA port. I guess it just needs a DVI to VGA connector. – Utkarsh Jain Nov 16 '15 at 18:16
  • I think it depends on whether the analog pins are connected. I recall there being digital-only versions of DVI where you need to implement different specs. – Vlad Nov 16 '15 at 18:20

    It is impossible to answer this question without more information about the FPGA board in question. Can you post the schematic of the connection between the DVI port and the FPGA? – alex.forencich Nov 16 '15 at 18:58
  • You need to write a new physical layer, which translates VGA signals into signals for the DVI PHY. – Paebbels Nov 16 '15 at 19:24

You didn't specify the board that you're using, but if you already have experience with VGA on FPGAs I assume that you don't have an VGA connector.

Maybe you can use an external IC to control the signals. Something like ADV7125. You can even get a dev-board for it.
