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.

TINA-TI
TINA-TI provides an extensive array of analyses, including standard DC, transient, and frequency domain evaluations within SPICE, as well as numerous additional functionalities. It features powerful post-processing tools that allow users to tailor their results to meet individual needs. With virtual instruments, it is simple to select input waveforms and investigate voltages and waveforms across different nodes in the circuit. The schematic capture tool is designed to be exceptionally intuitive, making it easy for beginners to get started quickly. Installing TINA-TI requires about 500MB of disk space, and the installation process is straightforward, which allows for hassle-free uninstallation if necessary. However, we are confident that once you explore its features, you’ll be inclined to keep it. Developed exclusively by DesignSoft for Texas Instruments, this free version maintains full functionality but does not include certain advanced features available in the complete TINA package. Overall, TINA-TI is an outstanding resource for both beginners and seasoned professionals who are looking to perform detailed analyses of electronic circuits. Users will appreciate the blend of simplicity and depth it offers for effective circuit evaluation.
