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.
