I was making adder circuits in games 8 years ago in an attempt to build a computer. I finally worked my way up and built a working computer!

• logisim-evolution

  25 4,307 9.4 Java

  Digital logic design tool and simulator

  

though i'd heavily recommend first building the circuit in a logic simulator like Logisim, or Digital before trying to build it in a game for an FPGA. (Digital even allows you to export circuits as Verilog/VHDL, and as a certified lazy person, that is very useful)

• customasm

  10 680 7.8 Rust

  💻 An assembler for custom, user-defined instruction sets! https://hlorenzi.github.io/customasm/web/

also if you start writing programs for your own CPUs, use something like CustomASM so you don't have to write in machine code.
