I wouldn't want to do that, GPU compilers are not open source and the hardware is undocumented. As a scientist I feel they are extremely badly designed. My transistor and atomic simulation software is extremely parallel but not in the

The full WSI with 10 billion transistors at 180nm has not been taped out yet, I need $100K investment for that. This has 16K processors and a few megabyte SRAM. I taped out 9 mm2 test chips to test transistors, the processors, programmable

Going outside of the PDK rules you risk contamination because a chip machine is a high speed ultra-accurate automated mechanical and chemical laboratory. It sprays extremely corrosive acids and vaporizes metals. Going a nanometer outside o

The best results will be with custom shapes and custom individual placement of every transistor outside standard cell but within the PDK rules. Going outside the PDK rules will be even better but also harder. The trial and error you do most

Maybe in therory, yes. In practise the fab will never allow you to do anything at your own risk because it might contaminate or break their $170 million machine. If you offer a few billion extra to cover that risk, your cheaper off building

no, the mask must be made within the tight rules of the proprietary (and very secret) PDK of the TSMC Fab for that node. Just getting it certified that it fits the rules will cost millions. https://en.wikipedia.org/wiki/

No. Actually, the state of the art of EDA software is worse. My project has been to design (and create) better EDA software that will simulate, optimize and therefore can form and place each individual transistor optimally to achieve lower

Yes, basic physics shows [1] that we can use (free space) optics instead of wires inside chips. This will improve energy use and speeds by 3 orders of magnitude. Next to a transistor you put a photon detector. You can flip the transistor wi
