Résumé du concours

Hi I am looking for help fleshing out an idea I have for a xilinx FPGA system. Unfortunately I don’t have the time to research this information myself.
I need advice on how to connect FPGAs together, The FPGAS are going to be on daughter cards. I need to connect them together with a bidirectional 100 MB/S link.

Part 1)
Consider 2 FPGAs, One is a Virtex vc5vfx30t The other is a vc5vlx50t . I believe I need to use the Rocket IO. The vc5vfx30t has GTX’s but the vc5vlx50t only has GTP’s
1) Can I join GTX’s to GTP’s? How?
2) Can I join the two FPGAs together via a backplane?
3) What sort of connectors can I use on the backplane (the data signal will need to go through two sets of connector) I prefer a plug and socket, Could you please specify part numbers (in stock at either Farnel of Digikey). FYI I will need other signals and power on the connector as well.
4) Can I connect the FPGAs directly or do I need some voltage translation (how)
5) What about clocking

Are there any special considerations for designing the PCBs (backplane & daughter cards)

Can I use coax cable , if so , what circuitry do I need. Is this preferable?

Part 2, In the general, Can you defined an interface that would work between any Xilinx FPGA (that has Rocket IO)

I might replace one FPGA with a Kintex or Virtex 6/7

Part 3 Same basic question but I only need a bidirectional 10 KB/S connection. And might not have any spare RocketIOs.

Many thanks for considering my project

Best regards

Hi Hope things are well, If you run out of space you might like to send a couple private emails with more details, I only found this trick out recently

Many thanks so far, Just to clarify I think the solution will need a back-plane
I have realized there are quite a few discussion points, so if you want to answer in the general but then concentrate on one or two in detail that might work very well
