The HardwareSimulator will supplement it with false (0). For the software, I need to make a compiler, a VM translator and an assembler. Nand(ain, btrue, outout) If we are only concerned with the input of ‘a’ we can supplement the input of ‘b’ with a boolean. IO means input-output, so keyboard-screen. Also need to make an IO manager and the IO itself (a keyboard interpreter and a video card). I need to create a CPU (including memory). Elements of Computing Systems, Nisan & Schocken, MIT Press,, Introduction slide 2. Like looking up breadboards on the site, aren’t these BBs cute? image: The starting point of our computer architecture is the Nand gate.

1 million bits which would translate to at least 2 million nand gates plus a significant amount more for taking card of muxing/demuxing and decoders for the ram. Simon has been looking at what stages the project would involve and what hardware he would need. Figure 1.7 A screen shot of simulating an Xor chip on the hardware simulator. If you then want to implement 256 Kbits for RAM, 128 Kbits for Screen and 512 Kbits for ROM in nand gates just as they do in the real project then you'd need a really bigass fpga. They say you can build everything from NAND and then they just throw in a new building block without explaining how it’s built from the building blocks they already built up. That just contradicts the whole premise of the thing though.

If you load your HDL and nothing show up in the HDL window in the simulator and you dont see an error message, this is probably whats happening.

On some computers with small screens these messages are off the bottom of the screen and are not visible. Now here is an interesting observation: normally, when you run a program on some computer, and you dont get the desired result, you conclude that the program is buggy. They confine a vague understanding of it to a technical note and call it “conceptually confusing”. The hardware simulator displays errors on the status bar at the bottom of its window. Screen. The Rect program illustrated above draws a rectangle of width 16 pixels and length RAM 0 at the top-left of the screen.

They basically say: “Here’s a D flip-flop, don’t worry about how it’s built”. One thing I don’t like about From NAND to Tetris is that they don’t explain sequential logic, like at all.
