Hi Xavier, For what it's worth, our SNAP2 collaborators in China made an FMC card with the 12 bit version of the ASIAA ADC chip. This might be a reasonable starting point if you don't want to go to wild with JESD.
The post-Virtex6 version of the toolflow (i.e., that used by SNAP / SKARAB) began life on a Kintex dev board -- the kc705, IIRC. It is trivial to get to the state where you can use the toolflow to make LEDs flash and compile a design with software registers. For more than that, (Ethernet/Memory interfaces) the complexity depends how much code reuse you can get away with. Eg., some tweaking of the CASPER 10GbE or SKARAB 40GbE core would probably get you going, but you'd have to be comfortable getting your hands dirty.
