What is CircuitSim?

CircuitSim is an extensive SPICE circuit simulation platform that boasts a collection of more than 3,000 components alongside a modern schematic editor, all available online for free without any installation requirements. It is tailored for students, teachers, and professionals, functioning directly within a web browser, which allows it to be used seamlessly on devices like Chromebooks and school-issued laptops that may have restricted access. Users can engage in seven different analysis types, encompassing both interactive and transient analyses, with results visualized on oscilloscope-style graphs, and they have the option to place probes throughout the circuit for detailed observation. The platform also enables the creation of custom components from SPICE model text and the import of symbols from KiCad, greatly enhancing the simulation experience and versatility. CircuitSim further facilitates the importation of designs from Multisim Live prior to its planned discontinuation on September 15, 2026, making it a distinctive browser-based alternative capable of handling .csim, .ms14, and .msjs files while maintaining wiring, component arrangement, net labels, probes, and simulation settings intact. Additionally, there are classroom licensing options that introduce features like seat assignments, anonymous student seating arrangements, and dedicated private project spaces for students, which significantly enriches the learning environment. This comprehensive approach ensures that educators have the tools necessary to effectively oversee their classrooms while taking full advantage of sophisticated simulation technologies.
