Multisim is a circuit simulation software that performs Multisim circuit simulation, Multisim schematic capture, and Multisim SPICE simulation to design, test, and analyze electronic systems in a virtual environment. This platform from National Instruments (NI), known as NI Multisim (NI Multisim), integrates SPICE (Simulation Program with Integrated Circuit Emphasis) to simulate analog, digital, and mixed-signal circuits with precision.
Multisim helps users create circuits, run SPICE simulation, and validate PCB design (Printed Circuit Board Design) before hardware production. The main benefits include accurate circuit analysis, access to a large component library, and support for transient analysis, AC analysis, and DC analysis. Engineers and students use Multisim for electronics workbench tasks, homework, lessons, and design projects such as power electronics simulation, RF circuit co-simulation, and signal integrity analysis.
The platform includes key components: a schematic editor, SPICE simulator, graphical user interface (GUI), and model libraries. These tools allow virtual prototyping, automated fault testing, and worst-case scenario analysis without physical components.
