Status Quo


No-touch FoundryMassive cloud computingChip Layout ArmyA General Purpose Silicon Compiler:

• Removes expertise barrier to democratizes access to silicon technology

• Replace finite human time with machine cycles

Outcome:

• Makes it practical to specialize for “N=1”

• Reach beyond the horizon, across the chasm,..
