CircuitSim features and specs

  • Free and accessible
    CircuitSim is a free, browser-based (and downloadable) digital logic circuit simulator, making it easy for students and hobbyists to access without any cost or licensing barriers.
  • Educational focus
    Designed primarily for teaching digital logic design, it provides an intuitive way to build and test circuits, making it popular in academic settings like computer science and engineering courses.
  • Simple, intuitive interface
    The drag-and-drop interface for placing gates, wires, and components is user-friendly, especially for beginners learning digital logic concepts for the first time.
  • Subcircuit support
    Users can create subcircuits and reuse them as components in larger designs, which helps in building more complex systems in a modular and organized way.
  • Open-source project
    CircuitSim is open-source, allowing developers and educators to inspect, modify, or contribute to the tool, and fostering community-driven improvements.

PartSim features and specs

  • User-Friendly Interface
    PartSim offers an intuitive and easy-to-navigate interface, making it accessible for beginners and those not familiar with complex circuit simulation tools.
  • Web-Based Platform
    Being web-based, PartSim can be accessed from any browser without the need for installation, making it convenient to use on multiple devices and platforms.
  • Free to Use
    PartSim is available for free, providing access to powerful circuit simulation tools without subscription fees or purchase costs.
  • Built-in Integrated Libraries
    It offers integrated libraries with common circuit components, which simplifies the process of designing and simulating circuits.
  • Real-time Simulation
    PartSim provides real-time simulation feedback, allowing users to immediately see the effects of design changes, which aids in faster prototyping.

Possible disadvantages of PartSim

  • Limited Advanced Features
    Compared to some advanced circuit simulators, PartSim lacks certain advanced features and customization options, which might limit experienced users.
  • Internet Connection Required
    Being a web-based tool, PartSim requires a stable internet connection, hindering its use in offline scenarios.
  • Performance Constraints
    For complex or large-scale projects, the performance and speed of PartSim might not be on par with dedicated software-based simulators.
  • Limited Component Database
    While it has a built-in library, the range of components available might not meet the needs of users requiring niche or less common components.
  • Lack of Community Support
    Compared to popular paid software, PartSim has a smaller user community, which might limit the availability of tutorials, forums, and troubleshooting help.

Questions & Answers

As answered by people managing CircuitSim and PartSim.

Why should a person choose your product over its competitors?

CircuitSim's answer

CircuitSim earns the choice when the constraint is the browser: students on Chromebooks, online courses, schools where IT will not install desktop software. Within that space, CircuitSim pairs true SPICE simulation with classroom licensing, private student seats that need no login, and an importer for Digilent's Multisim Live files.

What makes your product unique?

CircuitSim's answer

CircuitSim runs a real SPICE engine entirely in the browser. Simulation results match what desktop SPICE tools produce, with nothing to install. On top of the simulator there is a large searchable component catalog and classroom groups with private student seats: a teacher shares a join link and students work without creating accounts, which keeps classes clear of the student-privacy problems that come with provisioning accounts. CircuitSim also imports designs from Digilent's Multisim Live, which matters right now because Digilent is retiring Multisim Live in September 2026.

How would you describe the primary audience of your product?

CircuitSim's answer

Educators and students, mostly. The core user teaches circuits somewhere that desktop software is not an option: community college electronics programs, university ECE labs, online courses, and K-12 engineering classes where students are on Chromebooks. Outside the classroom, hobbyists and working engineers use CircuitSim for quick analog and digital simulation without installing anything. A large share of new users right now are instructors moving their courses over from Digilent's Multisim Live before it retires in September 2026.

Who are some of the biggest customers of your product?

CircuitSim's answer

Community college electronics and engineering technology programs University ECE departments running browser-based circuit labs K-12 engineering and CTE courses on Chromebooks Instructors migrating classes from Digilent's Multisim Live ahead of its September 2026 retirement
