AMD/Xilinx 7-series GTP question:
Has anyone used 10GBASE-SR SFP+ transceivers to link GTPs of two Artix 7 FPGAs on different boards?
In other words, I'm interested in using the transceiver as a "raw" optical interface at, say, 5 to 6 Gbps line rate, within the GTP specifications, rather than the 10.3125 Gbps that would be used for 10G Ethernet.
This obviously depends on the transceiver to be dumb, like an SR or LR, and not reformat the signal, do WDM, etc.

After exchanging on a #Sipeed channel about what I found with the Tang Nano 4K #FPGA examples and #HDMI output, someone, speaks me about it’s contribution of open source FPGA, with a generic FPGA HDMI driver that works on lot of FPGA (including #BlackIceMX, #icoBoard and #Icestick (both Lattice #ice40 based), #ColorLighti5 (Lattice LFE5U based), #ulx3s (Lattice #ECP5 based), #Arty7 (Xilinx #Artix7 based) and this one (Gowin #Gow1n4K based). The result is better than the official examples, and even work on my cheap (<10€) HDMI->USB acquisition device I had, where the official settings didn’t even display anything on this device. But It worked on my old computer monitor (using HDMI 2 DVI adapter).
He used DVI-PMOD that has about the same goal for a 12-pin PMOD expansion port found of lot of FPGA boards as a base for this clean and generic implementation.
Searching about what adapter supported, I found an open source FPGA project of HDMI2USB. I’m not sure my board HDMI could be used a reverse way, don’t know enough about it for now.
Tiny FPGA Board Fits In Your Laptop [Provided the laptop has a M.2 slot]
"There are a bunch of FPGA development boards to choose from, but how many will fit inside your laptop? The PicoEVB is a tiny board that connects to a M.2 slot and provides an evaluation platform for the Xilinx Artix-7 FPGA family."
