I&#x27;ve given them props before as they&#x27;re a special case. They wrote a whole blog article on how they kept things cheap. In comments in past 48 hours, they mentioned something like $2-3 million in 3 years to get their relatively simple design done. I also remember they deal with HPC crowd that pays good money for even low-volume.<p>So, they&#x27;re just unusual across the board. Doesn&#x27;t tell us much about a large design except to say physics will fight us every step of the way. Various approaches like asynchronous and self-correcting circuits might help us a bit. Look at Achronix FPGA&#x27;s to see the power of the former.
