However, scaling down a custom chip to 22 nm requires a complete rework of the design, yes? At least any analog parts if I understand correctly.

- zrobotics 4y agoDigital as well. Even if the overall design is similar, layout is dependent on the node size. Plus, the masks have to be remade at a not insubstantial cost.
- pjc50 4y agoAnalog subsystems will require rework from scratch; digital can usually keep the same HDL, and its associated test suite, but changing to much smaller standard cells completely changes the timing properties. So all the timing closure and layout work needs to be re-done. Budget about 50% of the original cost, approximately.
