About

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.

About

Simcenter PSIM is a Siemens simulation tool designed for power electronics and motor drive design. It helps engineers analyze power converter losses, motor drive efficiency, conducted EMI, and analog or digital control systems. The software has been used in the power electronics field for more than 25 years and combines a user-friendly interface with a robust simulation engine. Simcenter PSIM supports fast switching simulations, quick power loss calculations, and design suites for power supplies, motor drives, EMI analysis, filter design, and HEV powertrain systems. It also includes automatic embedded code generation, allowing teams to create C code from control schematics for rapid prototyping. With verification tools such as Monte Carlo, sensitivity, and fault analysis, Simcenter PSIM helps engineers design, test, and validate power electronics solutions faster.
