Does anyone know what the cost of these 28nm Artix 7 chips are? I've been looking through and the XC7A350T looks promising with 350k LUs. From the text on the site it looks like they're using this chip to replace the Spartan 6's.

I asume their cost ~~to be prohibitive~~(remember we want to create a system with low entry investions) but the most resticting feature is their avaidability wich is said to be even worse.I addtition we would need a full commercial license for ISE, so lets please stick with the FPGA we have voted on unless you get a highly competetive price quote.
Just for comparison a similar board you quoted exists already and is ~8500 Euro each.
Edit:I see they tell the price to be "at lower price points than Spartan®-6 FPGAs" but still we may use them on a sucessor to this project not now.

That deadline is reasonable for a prototype unit that is in the middle of testing and firmware bringup. I do not anticipate many issues with this type of design as it is a straight FGPA with ucontroller. Were any of the individual functions tested separately at least (power bus, etc) with proper loading? If not, we should do this as re-spinning the PCB would not be cost effective if there is a major issue on those smaller functions. I have a DC load tester (constant voltage or current) here as well as a decent scope that we can use.

No there hasn't been any testing of any real components so far.
I agreed we should individually test segments of our setup.Power supply should be easiest to do.
Maybe Li_gangyi could post his desired setup so you may have a look on it.

Further the BUS system needs individual testing.
