About CircuitSim
CircuitSim is a full SPICE circuit simulator with a 3,000+ component library and a modern schematic editor. No install, free to get started. Built for students, educators, and professionals.
It runs in a browser tab and needs no admin rights, so it works on Chromebooks and locked-down school laptops. Run seven kinds of analysis: interactive, interactive operating point, transient, AC sweep, DC operating point, DC sweep, and parameter sweep. Results plot on oscilloscope-style charts, with probes you can drop anywhere in the circuit. Define custom parts from SPICE model text or import KiCad symbols.
CircuitSim also imports Multisim Live designs ahead of that product's retirement on September 15, 2026. It is the only browser tool that opens .csim, .ms14, and .msjs files, and it rebuilds the schematic with wiring, placement, net labels, probes, and simulation settings intact.
Classroom licensing adds seat assignment, anonymous student seats, and private student work.

LTspice
Its graphical schematic capture interface allows you to probe schematics and produce simulation results, which can be explored further through the built-in waveform viewer. The key to most circuit designs is the speed with which you can reach an understanding of your circuit, its correctness, and its limitations. LTspice outperforms many other simulation tools and enables you to iterate your designs in minimal time. Keyboard shortcuts are an alternate way to invoke one or more commands in LTspice that would otherwise only be accessible by clicking through the menu or toolbar. Our extensive collection of technical resources tackles a wide range of LTspice topics. Learn how to use transformers, add third-party models, create, work with symbols, and more.
