Chips and systems out at end of Feb 2014 - that means tape out sometime in December 2013, which means you've only just, or have not yet started physical design. Without being well into the physical design stage how do you know what your power or performance numbers are going to be with any confidence?
We've started the design in June. The only difference between us and our competitors is that we do not give unrealistic time frames which we know we cannot meet.
We are confident that we will deliver sooner but we do not make promises that we might not be able to fulfill.
To put this in perspective, 13 months to build a lemon of a miner! Just about the same amount of time to build the Empire State Building.
