Show HN: Think Turing Complete, but you write the circuits in TypeScript (WIP)

Simten - Design hardware with TypeScript circuits

Simten lets you build computers from logic gates using TypeScript instead of dragging wires. As you type, the circuit draws itself, letting you progress from basic gates to CPUs that run C, accelerators, and even games. When ready, export to Verilog and flash your design onto real FPGAs. It's a unique, code-first approach to hardware design that bridges software and silicon.

Build a computer from logic gates, one layer of abstraction at a time, by writing TypeScript rather than dragging wires—the circuit draws itself as you type.
