How does one use arrays (representing busses) in HDL? For example, I have the following code: /** * 16-bit bitwise And: * for i = 0..15: out[i] = (a[i] and b[i]) */ CHIP And16 { IN a[16], b[...

I am doing a parser for nand2tetris project. I want to check if the destination field is either M|D|MD|A|AM|AD|AMD and their different ways of combinations like MA not only AM. ^(M|D|MD|A|AM|AD|A...

i'm not too sure why my Nand2tetris simulator keep telling me line 3 error. can anyone tell me any problem with the following code: CHIP Xor { IN a, b; OUT out; PARTS: Not(in=a, out=not...

It's seemingly close to working, it just is messing up at line 7 apparently? /** * 4-way demultiplexor. * {a,b,c,d} = {in,0,0,0} if sel==00 * {0,in,0,0} if sel==01 * {0,0,in,0} if sel==10 * {...

So I'm working on the nand2tetris project, and I want to implement shift right logical on a software level since the hardware doesn't support it. I know shift right logical is a division by two. S...

I am reading and studying The Elements of Computing Systems but I am stuck at one point. Sample chapter skip the next 5 instruction s can be found here. Anyway, I am trying to implement a Virtual...

Is it possible to write logic using only the AND, OR, and NOT operators to compare 2 operands and return true/false (-1, 0) without the use of jumps? If so, can you please give me some hints as it ...

Although I tagged this homework, it is actually for a course which I am doing on my own for free. Anyway, the course is called "From Nand to Tetris" and I'm hoping someone here has seen or taken th...
