Comedi: Open Source Circuit Design and Simulation Software
Comedi is an open source circuit design and simulation software. It provides a simple interface for designing circuits and running simulations to analyze performance. Features include a component library, waveform viewer, and SPICE integration.
What is Comedi?
Comedi is an open-source software solution designed for circuit simulation and printed circuit board (PCB) design. It provides a user-friendly, interactive interface that allows electronics hobbyists, students, and engineers to easily design, test, and visualize electronic circuits.
Some of the key features in Comedi include:
- Intuitive schematic capture with a drag-and-drop component library for rapid prototyping. It comes preloaded with thousands of ready-to-use parts from resistors and capacitors to complex ICs and microcontrollers.
- Seamless SPICE integration for accurate analog and digital circuit simulation. Users can perform DC, AC, transient, and Fourier analysis with just a few clicks.
- Powerful PCB layout and routing capabilities for turning circuit schematics into professional-quality boards ready for fabrication.
- Customizable post-simulation analysis with a virtual oscilloscope, multimeter, signal generator, and Bode plotter for visualizing circuit performance.
- Support for hierarchy, version control, design reuse, and collaboration for improved productivity and organization.
- Outputs including netlists, Gerber files, Bill of Materials (BOM), and documentation to streamline the manufacturing process.
- Cross-platform compatibility with Windows, Mac, and Linux plus an active community forum for assistance.
In summary, Comedi combines schematic capture, simulation, PCB layout, and analysis tools in one integrated, freely available platform. It is an excellent choice for electronics designers looking to take projects from concept to fabrication.
