Interactive Circuit Simulator

Real-Time Analog, Digital, and Power Electronic Simulation

Welcome to the Papillon Engineering interactive circuit laboratory. Use the simulation workbench below to build, wire, and analyze DC/AC circuits, filters, and operational amplifiers.

Note

If you prefer an isolated workspace or are presenting in class, you can open the simulation in a dedicated full-screen window: Launch Full-Screen Simulator ↗

Quick Instructions

Placing Components: Use the top menu (Draw > Passive Components or Active Components) to select resistors, capacitors, sources, and semiconductors.
Wiring: Click and drag your mouse between component nodes to draw connection wires.
Control: Use the buttons on the right to Run/Stop the simulation or Reset the workspace.
