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

ProtoFlow is an advanced electronic design automation (EDA) tool specifically designed for schematic capture and PCB design, utilizing AI technology. It allows users to describe circuits in straightforward language, which generates an editable initial draft, enabling the search for actual electronic components and their footprints, along with datasheet inspections to ensure accuracy. Users can tidy up wiring and seamlessly continue working in familiar schematic and board editors. The tool includes features such as ERC/DRC reviews, 3D board visualization, Git-backed version control with visual diffs, collaborative comments, and outputs for manufacturing, which encompass Gerber files, drill files, BOMs, and placement files. Importantly, designs are maintained as editable geometries, and it is crucial for users to double-check symbols, footprints, connections, and manufacturing details prior to production. Additionally, ProtoFlow has the capability to read and write native KiCad files, allowing for easy integration into existing EDA processes. A free plan is accessible without the need for a credit card, while paid plans offer enhanced AI capabilities. This tool is tailored for hardware engineers, makers, students, educators, researchers, and startups in the electronics sector, making it a versatile choice for various users in the field. Furthermore, its intuitive interface and collaborative features make it an ideal option for teams working on electronic projects.
