LTspice

LTspice provides a complete environment for designing and analyzing electronic circuits. It includes a schematic capture tool that lets users draw circuit diagrams, a SPICE engine that performs transient, AC, DC, and noise simulations, and a waveform viewer for examining simulation results. The software supports a wide range of component models and allows users to define custom symbols and parameters.

Targeted at engineers, hobbyists, and students who need to verify circuit behavior before building hardware, LTspice offers an integrated workflow from schematic entry to result analysis. Its stable release status indicates a mature codebase that has been refined over time.

The application runs on macOS, delivering the same simulation capabilities available on other platforms while leveraging the operating system’s native interface. Users can export data, plot multiple signals, and perform parametric sweeps within the same environment, facilitating iterative design and testing.
