Hi,

  I am trying to use Coregen to create a GTX setup for the SD-SDI Protocol.  There is no option to choose

this protocol using Coregen.  How would I create a GTX for SD-SDI.

Thank You,

  Gary

Gary,

Which FPGA family with "'GTX"' transceiver - V5 FXT/TXT, V6 or K7/V7?

From a practical perspective, the difference may be important in terms of what is/will be available.

For example, for V6, I would start here instead of  CoreGen's ArchWiz

http://www.xilinx.com/support/documentation/application_notes/xapp1075_V6GTX_TripleRateSDI.pdf (Implementing Triple-Rate SDI with Virtex-6 FPGA GTX Transceivers)

This is a much better starting point for multple reasons.

Cheers,

Hi Barriet,

I am using the fx130t chip (Virtex 5) same as the ML510 board.   It seems that the SD-SDI might be slow for the GTX interface

because I don't see how to select it.

Thank You,

  Gary

I should have also mentioned that this V6 SDI GTX app note was later updated & integrated into CoreGen delivery flow.

In 14.1, you'll find a "Triple Rate SDI" core in CoreGen under Video & Image Processing.

For V5, I would start here:

http://www.xilinx.com/support/documentation/application_notes/xapp1014.pdf (Audio/Video Connectivity Solutions for Virtex-5 FPGAs)

Chapter 4 for GTX SDI.

Note that there is also an associated set of design files here for this app note. There should  be a link in the app note. i think you'll find this a much better starting point than CoreGen Arch Wiz... ;)
