Even simpler CPLD are so complex that you can't program them directly. You define broadly what you want and then a software make the programming for you. Yes, this is not internal to the CPLD or FPGA, it is done on a computer-like system. A brain on FPGA would have to include such a computer to manage the program making, that is, the brain evolution. About references, a basic one on the subject is : "Circuits logiques programmables" by Alexandre NKETSA, sorry it is in french. You could see too the data books from chip makers, for example AMD. I agree that a brain simulation system must work, for the outside world, as a brain. It is designed for that in the first place. Now, would it work 99.999 percent as a biological brain or 100 percent as such, nor you or me can tell. We have to build and test such a system to see. Now if you think a biological brain would be better, ok but how did you build it? How to produce a copy of a given brain? The difference is here: We can buy FPGA and programming computers, we can't buy a brain copier. I'll give a look at the books you suggest. Thanks for the references. Yvan Bozzonetti.
