How many IC samples are required to do a layer-by-layer reverse engineering of something at single-nm feature sizes? Ok, now you've got "something" here even resembling a netlist (lol), what do you do with it? Keep in mind: you don't actually have the manufacturing technology to use this IP. By the time you do, the IC you reversed is no longer state of the art. I think state-sponsored corporate espionage would be a lot more fruitful and cheaper.
