When somebody would make a free processor, would it be possible to do that in such a way that it's possible to check that the hardware is the working-out of the drawings?
Not so much my field but I'd say a precondition would be that you can produce a digitalised photographic (/holographic) representation of the chip you hold in your hands. To analyse multilayered chips you would grind them down in the process.
Or maybe you can image them in some kind of MRI...? Then you could at least match your chip against the image of a prototype. Can a microprocessor survive the MRI process? Are MRI resolutions high enough to make the structures visible, at least for past generation chips? Are the materials in the processor suitable to produce a clear image?
At least MRIs are getting more and more common. Maybe someone on the list has experience in working with one.
Just a funny idea.
