Earlier quoted context omitted.

makes sense, adding to the next push (in the interim, u can also use the copy circuit button to ask gpt if ur correct or not), also, what level is this? (if u dont mind me asking)

Oh that's what the "copy circuit" button does. I have been trying to paste circuits from previous levels into subsequent ones and wondering what I was doing wrong

lol, mb; ill make that more clear (ill also give the ability to copy things cross level and intra-level)

Hi everyone, commenting to address feedback: - Made timed minigames optional (e.g. binary tables) - Added 7 (optional) intro levels to walk through pmos and nmos transistors - Fixed the bug in the capacitor levels - Changed editor bg to use dots instead of lines to fix wire confusion

Layout appears unusable on my phone on Firefox Android (both portrait and landscape). Necessary elements seem to get hidden behind others. Not sure if I'm even supposed to be able to play it without kB&m though lol :)

Yeah, its not mobile-ready atm, ill push an update to make it mobile-friendly in the next day or so

Is this a sequel to "How to make a CPU"? https://www.youtube.com/watch?v=vuvckBQ1bME

lol, I hadn't seen that video before but its a good one. Na, this is the guide to comp arch that will (hopefully) end all instances of toil over documentation for any sort of processor when learning

...why capacitor has 3 pins ?

Yeah, I had added it to make it compatible w/ my simulation system, just changed how I was handling the levels altogether, if it still has 3 try doing a hard refresh (Ctrl + Shift + R on windows, cmd + shift + R on macos)

So, is there anything about GPU's in here right now? I didn't actually finish Act 2, but it seems to end in a conventional processor with the GPU first coming after another two acts currently under construction.

Not at the moment unfortunately, I've actually completed a good chunk of the GPU levels, but I think ppl will need to do act 2 and 3 for it to make sense

level 1.10 I put 2 AND gates and only one of them works...

I want to fix this, could you elaborate a bit (would help even more if you pressed the copy circuit and pasted the result here)

Add 2 AND gates, 1 NOT gate

G0 = D0 AND SEL

G1 = NOT SEL

G2 = D1 AND G1

G0 -> Ans

G2 -> Ans

I'm confused about a difference in the NMOS and PMOS. The scenario I'm confused about is when the source is VDD and the drain is connected to GND and output. For the PMOS, the output toggles between 1 and 0 (opposite the gate) as expected. However, for the NMOS, the output is always 0. I don't understand why GND pulls VDD down to 0 for the NMOS, but not the PMOS.

Oh, the drain should only be connected to the output, not drain aswell (irl this would kill one's chip, I'll add a feature to show short-circuiting). on pmos the source should be vdd, on nmos the source should be gnd (this doesn't apply for some later levels, but does for earlier ones).

The 2.13 level ("hex racer") is kind of pain. Apparently I'm not fast enough at dividing/multiplying by 16... when I get something like "convert 0xB3 to decimal"

Time to get on zetamac (all jokes aside, it should be optional, i'll also make racer games slower + adaptive soon (today))
