Description

CircuitSim is a comprehensive SPICE circuit simulation tool featuring a library of over 3,000 components and a contemporary schematic editor, all accessible online for free without the need for installation. Designed for use by students, educators, and professionals alike, it operates directly in a web browser, making it compatible with Chromebooks and secured school laptops without requiring administrative access. Users can perform seven types of analyses, including interactive and transient analyses, with results displayed on oscilloscope-style graphs and the ability to place probes at any point in the circuit. Additionally, users can create custom components from SPICE model text or import symbols from KiCad, enriching the simulation experience. CircuitSim also supports the import of Multisim Live designs before its scheduled retirement on September 15, 2026, making it a unique browser-based solution that can handle .csim, .ms14, and .msjs files, preserving wiring, component placement, net labels, probes, and simulation configurations. Furthermore, classroom licensing options are available, providing features such as seat assignments, anonymous student seating, and private student project spaces to enhance the educational experience. This ensures that educators can effectively manage their classroom environments while leveraging advanced simulation tools.

Description

Real-time collaboration, a simple simulator and forkable community content make it easier to build hardware more efficiently. Modern sharing, permissions and an easy-to use version control system allow you to harness collective intelligence. We believe in open-source. Flux's ever-growing library of schematics and parts makes it easy to get started quickly. Finally, a programmable simulation that doesn't require a PHD. You can view your schematic online before you start building. Flux is the place to go for great hardware projects, no matter if you're designing hardware for the next Mars mission or a simple circuit board. Flux is a browser-based, end-to-end electronic design platform that breaks down all barriers. Flux is doing something new and we're doing it in a unique way. It's called building openly. Join our community of makers, engineers, and entrepreneurs who are passionately interested in improving hardware design tools.
