Unprompted review
While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more
To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience. We recognise we may not catch everything, and you can flag anything you think we may have missed. Read more
Company details
Written by the company
CircuitSim is a browser-based circuit simulator with a real SPICE engine, a library of 3,000+ simulating components, and seven analysis types including transient, AC sweep, and parameter sweep. There is nothing to install: build a schematic, run it, and share it from any device, including Chromebooks. Teachers get classroom groups with private student seats that work without a login, keeping classes FERPA and COPPA compliant. CircuitSim also opens Multisim Live circuit files directly in the browser, so former Multisim Live users can keep working on their existing designs. Free to start, with affordable paid tiers.
