Engineers wanting a program to design and simulate switching power electronics systems
About SIMetrix/SIMPLIS
It combines accuracy and speed in a full-featured design environment, enabling 10-50x faster simulation than SPICE for power supply designs. All features of SIMetrix Classic and uses the same GUI environment including its hierarchical schematic editor and waveform viewer. Rapidly locates the steady state operating point of a switching system without having to simulate the startup transient conditions. SPICE transistor and diode model conversion to SIMPLIS format. Converts SPICE models by running a SPICE simulation to perform parameter extraction. The advanced digital simulation library provides a wide variety of digital functions such as counters, ADCs, DACs and much more.

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.

NL5 Circuit Simulator
There are plenty of circuit simulators available on the market. Just read their ads: high performance, extremely fast, industry-standard (i.e. SPICE), easy to use, highly intuitive. If you want to see if a tool is worth using, try it yourself. That's what many NL5 users already did. I hope they will share their encouraging stories soon. A few words about what should you expect from NL5. It is not one more SPICE (and not even close), nor is it a SPICE replacement. For some tasks NL5 is far superior, for others simply good, and some tasks are not for NL5 at all.
