Real-time Circuit Lab

Validate every node before fabrication

Load reference schematics or sketch new ideas, then inspect voltages, currents, and timing to ensure PCBs behave as expected before ordering builds.

Intuitive schematic editor

Drop resistors, ICs, sensors, and sources, then wire them with smart snapping and keyboard shortcuts.

Deep analysis modes

Run transient, AC sweep, Fourier, and parametric scans to inspect waveforms, gain, and noise.
