Usually one can expect half of octopart prices. So the difference would be about 30$ On 29 June 2017 at 21:43, Joe Britton via ARTIQ wrote: > Octopart Avnet costs for 1 unit > > XC7A100T-2CSG324C $131.22 > XC7A50T-2CSG324C $74.98 > > Greg, What is the cost differential

Octopart Avnet costs for 1 unit XC7A100T-2CSG324C $131.22 XC7A50T-2CSG324C $74.98 Greg, What is the cost differential between 50T-2 and 100T-2 assuming Xilinx open source pricing? -Joe ___ ARTIQ mailing list

Sébastien, Given the relatively low cost of the Artix-7 FPGAs, my preference is generally to go as big and as fast as reasonably possible. I don't want to find that, for example, we can't fit a hard FPU/fancy servo on Kasli because we saved $50 on the FPGA. Also, since gateware development is
