The open-source lab bench for digital logic — designed for desktop and laptop computers.

Desktop or Laptop Recommended

Klyro is a high-precision digital electronics lab bench. Placing 20-pin DIP ICs, precision Manhattan breadboard wiring, and real-time waveform timing analysis require the keyboard shortcuts, mouse accuracy, and screen space of a desktop or laptop.

Also available as a Windows Desktop App.

Everything you need to learn Digital Logic

One platform. Real tools. No textbook required.

IC Circuit Board

Place real 74LS and 74HC series ICs on a virtual breadboard, wire them up, and simulate logic behavior instantly.

Logic Minimization

Solve K-Maps up to 5 variables using Quine-McCluskey. Get simplified SOP and POS expressions in one click.

Waveform Viewer

Watch timing diagrams update in real time as you simulate your circuit — catch glitches and propagation delays visually.

FSM & ASM Charts

Build finite state machines visually with a drag-and-drop editor, then auto-generate clean ASM flowcharts from your design.

HDL Export

Export any circuit or FSM to synthesizable VHDL or Verilog with one click — ready for Quartus or Vivado.

Learning Mode

Follow step-by-step walkthroughs for every topic, attempt embedded quizzes, and track your progress as you go.
