I think I found the reference design you were mentioning. It is definitely not straightforward from TTK 2 Gbps reference design to 6 Gbps and this should be included in TTK links. The Altera wiki doesn't show this link in normal places but searching for Seriallite gave a result.

Now the challenge seem to be running the design internally in X95 as a standalone. I don't have external memory in my design.

If you have suggestions, comments or anything, please let me know.

Thanks,
