XAUI Phy in Stratix IV GX

Hi Jens,

Dave, you are right. The bytes are swapped. Also in some cases the alignment is not correct.

Ok, so this is a XAUI synchronization issue then.

I have not used the XAUI core.

After each reset the byte order is random. In the attached screenshots you see also the misalignment.

I'd recommend putting a Modelsim simulation together. Its a lot easier to probe signals and change things there.

Dave, do you have an example with XAUI running on the Devkit and loopback adapter? I could compare it with my implementation.

I'm sorry, but I do not.

Perhaps someone more familiar with the operation of the XAUI core can comment on how the link is supposed to be synchronized.

Cheers,

Dave
