There's still clones being made today of the YM2149, I think! Which is nearly a drop-in replacement for the AY-3-8910.

(And there's definitely reverse engineered Verilog/VHDL for it if you're down to waste an FPGA on DIY-ing it.)

1. 構成可能なブロックを1種類だけ用意する
- 6方向全てでRS信号の入出力を可能とする
- デジタルなら1本1bit
- アナログなら1本4bit
2. 構成方法を用意する
- VHDLでいい感じに記述できたらいいな
3. 楽しむ
- LUTもALUもADCもなんでも作れる

どうよ

Quand on écrit du code, qu'il a l'air clair, aéré, concis, joli et tout ça, ça ne prouve pas qu'il va marcher mais c'est plutôt bon signe.

Avec le VHDL, curieusement, c'est tout l'inverse. Quand c'est joli, fluide et agréable à lire, c'est louche, et en général, ça plante direct.

even when i write a shotgun parser, i put source location support into it :p

this is a source location for a string embedded in a VHDL container, which is why it has a weird 'filename'

TBF my definition of "full stack developer" does include VHDL

You pretty much can; learn VHDL (my preference) or Verilog (probably more community support available), and use it to program FPGAs with your design.

Once happy, do gate-level synthesis, g-l simulation, and once happy send to tinytapeout.com for fab.

Ok, it's not *easy*, but it is possible.

You're never too old to learn FPGA programming with VHDL or Verilog
You're never too old to start making indie games.
You’re never too old to start drawing.

Respekt! Da investiert jemand ein Jahr Zeit, um die originale NES-CPU in VHDL nachzubauen: https://hackaday.com/2009/10/17/nes-processor-cloned-on-a-fpga/

New post on downloading and installing "free" Intel/Altera version of the excellent ModelSim Questa VHDL+Verilog simulator. I've been using this simulator professionally for 30 years now and it's great to have it up and running at home for hobby projects.

Meanwhile his AI completely failed when he asked it to write a simple block of VHDL code.

デジタル回路設計法って講義があったんだけど、回路設計の勉強ができる!!って思いながら履修したらVHDL書いてFPGAで遊ぶって講義だったっていう。(わざわざ私物のPCに開発環境入れて講義前に講義の内容終わらせてから講義に行くくらい楽しかった)

Standards are open via standards bodies, proprietary to companies, and de facto. Examples include networking protocols like TCP/IP, HTTP, and SMTP; file formats like HTML, JPEG, and WAV; OS interfaces like Win32, POSIX, and Cocoa; and hardware languages like Verilog, VHDL, CUDA, FPGAs, etc.

Looking at Verilog too much? Switch things up a little with some VHDL! ;)

I've done most of the languages on your dread list, and none on your preferred list. Also work with hardware languages, Verilog and VHDL.

It seems you got inspired by my thesis from 1997 😀 I however wrote models in VHDL for Actel FPGAs...

Hardware Design Languages (like VHDL or System Verilog) often bend software folks brains, and are good at their purpose, but said purpose means many software folks don't need to know them either.
