Show HN: A game where you build a GPU

This seems really cool, haven't played it yet but I took a glance at the first two levels and it looks similar to another game I've played - will definitely play through it when I get a chance. I wanna make a GPU but my board doesn't have nearly ennough dsp units, so a virtual one like in this game will have to suffice lol

This reminds me of the Zachtronics game KOHCTPYKTOP (https://zachtronics.com/zach-like/). The game left me wanting more and wishing I was using an actual tool for learning or designing semiconductors circuits, rather than playing a game.

It sounds great, it remembers to me:- https://www.nand2tetris.org/- https://nandgame.com/

Neat idea!Ive added this to the HN Arcade! https://hnarcade.com/games/games/mvidia

You need to have a, "Okay, I've tried 10 times, it's not working, what's the answer?" button. That will help not just us rubes who can't understand, but also in the off chance something is broken and even "correct" answers are being rejected.

At the end you have your own CPU with your own assembly language.
Sadly stuck in early access since forever with some very rough edges

I worked on deep sub-micron, full custom mixed-signal integrated circuits for more than a decade, and I can't pass the first level.> Wire an NMOS transistor so that when In is 1, the output is pulled to ground (0). When In is 0, the output should be unconnected (Z).Certainly:(a) The nMOS has 3 connections: its drain is only connected to the output (no +Vdd supply), it's source is tied to ground, it's gate is tied to the signal input(b) When the gate (input) is driven high, the nMOS transistor turns "on," connecting the output to the source (which is grounded). This acts as a "pull-down network"(c) When the gate is driven low, the nMOS turns "off," leaving no connection to the output. This is equivalent to a "high-impedance" / "unconnected" / "Z" outputFails 1/2 tests(Edit) - I thought the light grey, thick line on the background grid was a wire from "input" to the transistor's gate. It is not. You need to explicitly add a wire from "input" to gate :\

This is great!Some comments:- I didn't like the "truth tables" one, I got many duplicate questions and for some reason I got only one second for the first question. The rest of the questions I managed to answer correctly but I still got only one start out of three?- I got very confused by the capacitor. Capacitors do not have an "enable" gate! In fact, in 2.7 (1T1C) you are supposed to build the enable gate -- with a transistor. So currently, you can just simply not build the enable gate and use the one already in the primitive, meaning you don't need the NMOS gate at all.Was this made using LLM-assistence? (Not judging, I'm just interested!) I'd love to hear more about your workflow and how you managed to produce a good UI as it's something I couldn't do if my life depended on it, and it's a skill I'd like to learn.

This looks really cool, although I personally seem to lack the absolute basic knowledge that is required to make sense of the tutorial messages, so I couldn't even figure out the first level.
