The application
Simulate circuits without sending them to a server.
Your schematic, models, values, and waveforms stay on your computer. Everything runs in your browser, with no account required.
What you can do
- BuildDraw a circuit or import a supported SPICE netlist. The import report clearly lists anything that changed or is not supported.
- SimulateRun startup and periodic steady-state simulations on your computer.
- AnalyzeView waveforms, add calculations, use cursors, take measurements, view FFT results, and compare parameter values.
- SaveSave projects in your browser and export project files, netlists, schematic images, and reports.
