Logicarium

Run high-performance logic simulations directly in your browser without breaking your flow.

  • Local, because simulations need direct access to your compute resources.
  • Native, because it should actually feel like it belongs on your desktop.
  • Flexible, because some circuits take seconds and others take hours to perfect.

Built for your productive work

  • Design with code. Describe your circuit architecture in plain text DSL and watch it render instantly.
  • Real-time simulation. Watch logic signals propagate as you edit, with zero latency.
  • Verify with confidence. Every change is tracked, highlighted, and validated by the engine.

Engine Benchmarks

Measured on WASM engine (Browser). C++ Native performance is ~10x higher.

Frequently asked questions

Which circuit types does Logicarium support?

Supports combinatorial, sequential, and hybrid digital logic circuits up to 10M gates.

How do I use the DSL?

Use the built-in editor to define components. Syntax is similar to Verilog but optimized for rapid drafting.

What is Logicarium built for?

Academic research, rapid prototyping, and digital logic education where performance matters.
