Hi, I am interested to connect two FPGAs on my PCB and I want to achieve 40 Gbit/s data transmision. Any ideas what kind of connection should I use to achieve that speed? Maybe someone of you have already done it?
which FPGA? How much knowldege do you have? Some FPGAs offer serdes blocks which are capable of up to 32Gbit/s per link. But those are complicated and have many requirements regarding routing quality.

You want high-speed as easy as SPI? What´s yor problem?
@Schlumpf I have no problem, i want to help komo. Either you have a problem to distinguish between me and Komo or you see to be very rude. @Komo Some more information would be helpfull. But to work with an design which processes 40 Gbit/s will bring some surprising difficulties for you. best regards

Xilinx offers you FPGAs with high-speed serdes. For 40 gbps (pure net rate?) you will currently need multiple lanes. It is useful to pack a lightweight protocol core like Aurora on it. There you can combine 5x 10,3Gbps links and have a nice streaming Interface on both sides.
