LogicForge is a digital logic simulator with exactly two parts: NOT and AND. Everything else – OR, XOR, adders, memory, a whole CPU – you build yourself, block by block, and watch the circuit compute live.
LogicForge ships no ready-made building blocks. There is NOT and AND – and everything grows out of those: OR, XOR, multiplexers, adders, registers, an ALU, and finally your own 8-bit CPU with an assembler.
One key turns any circuit into a component in your library, ready to be used as often as you like – nested as deep as you like. The live view opens any instance and shows its inside with the real values.
102 chapters in fifteen acts across three worlds – circuits, assembly, Python – each with its own character that grows as you progress. The goal is given, the solution is yours to find, and stars reward correctness and economy. Every block you solve (OR, XOR, adder, ALU, flip-flop, register, counter …) sits ready in your library afterwards.
Truth tables, waveform view with cursors, halt conditions, keyboard, terminal, screen, RAM/ROM, Verilog export and import, Arduino export of the finished circuit, and an import for Logisim files.
