A fairly large amount of work is required to re-map the design onto Intel standard cells, which are not compatible with others. This means entire backend needs to be re-done. It's very significant amount of work.
- floxy 5y agoWhy would they port them to use new standard cells? Why wouldn't they just use the existing physical layout artwork to make new masks (i.e. GDSII files)? Assuming a closely compatible process. Maybe that's the catch? Intel's existing processes aren't close to anything anyone else has? Not that I think 6-9 months is reasonable.
- dboreham 5y agoBecause the layout depends on the process. And processes are different.
- BooneJS 5y agoIf it’s just standard cells, then it could go quick. Change technology library and synthesize. But if there’s process-specific IP (analog serdes, non-standard cells, etc), then that takes work. I presume most automobile chips are not leading node high-speed switches.
