In a hilarious move Buttlefly Labs is blaiming Global Foundries for the delay of their new Bitcoin miners. This Ars Technica article follows their exploits. I previously blasted Ars for doing a paper launch product review of one of Butterfly Labs products. They have to be kidding if we are to believe that AMD's former fab, which made high end CPUs, can not manufacturer a simple ASIC that is a whopping 65nm part.
Max Baker, a San Francisco Bay Area electrical engineer with extensive experience in FPGA and ASIC chip design, told Ars that because BFL's wafer size is at 65 nanometers, an experienced company shouldn't have these kinds of yield problems in manufacturing.
"There's more likely problems with their design," he said. "I'd say if you had all the manpower resources you need, and all the tool sets you need, and relationship with the foundry, you'd be lucky to spin an ASIC in 9 to 12 months. That's having everything lined up. If you have problems, it will take you longer. [If BFL is unfamiliar with those realities,] it would be easy to underestimate the tools that are required in order to get it done."
I think almost anyone that reads this site could have told you that.
