Aurora loopback between two transceivers in the same tile ML507

[rsahakian]

Hi,

I am trying to implement an Aurora link between the two transceivers in the X0Y3 tile of the ML507 (XC5VFX70T) board. I am trying to complete a loopback test over a SATA link. How many Aurora cores would I need to generate? My understanding is that each Aurora lane/channel uses one transceiver so I would be needing two separate Aurora cores. I am not sure how i would combine them in a single project. Any help is appreciated.

If you are planning to have the same line rate and ref clk frequency for both the tiles, then you can generate a single aurora core with two lanes.

refer to Appendix A of ug353

The issue here is that both transceivers are in the same tile so i can't just generate a core with 2 lanes.

You need to generate two cores and stitch them together (by manually editing) to make use of single dual tile.

Refer to the link provided by @venkata.

I have looked into that portion of the UG but I am not sure about how to implement the stiching of the two cores in one project. Do i have to re-label signals of the individual cores on the top level and connect them at that level? Any previous work that i can take pointers from?

Yes. You will need to re-label signals of the individual cores on the top level and connect them at that level

hi,
I am doing the same thing with PCIE protocol. How can I write the UCF file for loop back testing and is there any jumper setting for loop back ?

[venkata]

can you create a different post in PCIe board?

Hi, 

My problem is wtih GTX & SATA . Anyways give me thread of PCIE 

Thanks

In the previous post you mentioned about PCIe. This is why I have told to create topic in PCIe board.

If it is between GTX and SATA, then create a new topic in this board itself.
