People have replicated silicon fab processes at home -- see e.g. [0] where Jeri Ellsworth makes homemade transistors. Of course the effort she took to do that (while seriously really impressive) probably isn't worthwhile compared to the use of an FPGA if you just want to see your CPU pipeline in Verilog come alive :-) [0] http://hackaday.com/2010/05/13/transistor-fabrication-so-simple-a-child-can-do-it/ http://hackaday.com/2010/05/13/transistor-fabrication-so-sim...
