@gilesgoat That's an interesting question. Companies never expose the full details of their chips. The one exception that I know of is that someone talked Intel into releasing the masks for the 4004 processor: https://4004.com/mcs4-masks-schematics-sim.html
@kenshirriff @gilesgoat There is a story of a Russian chip that obviously reverse engineered a TI chip since the TI logo is on the chip. There is also a story of a RE chip (PDP-11 I think?) with a Russian something to the effect "steal from the best"
Later chips and the piracy race made it much harder ...
