Nexys video signal integrity information

[toby]

Hello,

I am prototyping a concept on the Nexys Video Board.

I would like to use the FMC connector and build my own FMC-like board.

I will be using both GTP and SERDES outputs. considering the speeds (2.4Gbps, 300Mbps)  I need to make sure signal integrity is up to standards all the way from FPGA Ball to the chip on my FMC board including connectors and co.

Therefore I need info on the Nexys Video Layout.

could you provide:

-full layout so I can do post-layout model extraction for the GTP and SERDES io lines, for simulation with Hyperlynx?

   or

-hyperlynx models of the lines?

best regards.

Hello Toby,

 

Unfortunate, we cannot provide the full layout of the board and we do not have hyperlynx models of the lines. What I can tell you is that it respects the FMC standard 50Ohm impedance for single ended and 100ohm impedance for differential traces. 

Also I can give you the traces length for the FMC connector so you can calculate the speed.

Attached here you can find the traces length. I hope this helps!

 

Best regards,

Bianca
