I am about to embark on a project, enspired by Nand2Tetris (http://www.nand2tetris.org/), to fully simulate a computer, building the entire thing up from NAND gates.
I want to simulate everything from scratch, starting with a primitive implementation of a NAND gate that simulates how a NAND gate would work on the physical level, and then connect them together to build a computer.
The thing is, I don't understand enough about how a NAND gate would work on the physical level in order to write this.
To be clear, this is certainly not what I am looking for:
def nand(a, b) return !(a && b) end
I'd like to implement the NAND gate as a class, so it functions more like an actual object. I'd like it to have pins, and I'd like to be able to connect the pins together and apply voltage, etc.
Can someone show me how you might implement a proper simulation of a physical NAND gate, one that could be linked together to ultimately build a computer?
