Gnucap: Free, Open-Source Circuit Simulator
A free circuit simulator for Linux, Windows, and Mac, allowing design, testing, and analysis of analog, digital, and mixed-signal circuits.
What is Gnucap?
Gnucap is a free, open-source circuit simulator and schematic capture tool for Linux, Windows, and Mac operating systems. It allows electronics engineers and hobbyists to design, test, and analyze analog, digital, and mixed-signal circuits without having to physically construct them.
Some key features of Gnucap include:
- Simulator engine optimized for analog circuits, with support for digital circuits as well
- Intuitive schematic capture interface for drawing circuit diagrams
- Support for SPICE-like netlists for defining circuit connectivity
- AC, DC, transient, Fourier, noise, distortion analysis types
- Models for transistors, opamps, logic gates, passive components, transmission lines
- Monte Carlo and worst-case analysis for tolerance studies
- Scripting and batch mode operation for automation
Overall, Gnucap provides a capable, easy-to-use, free alternative to commercial SPICE simulators for engineers, researchers, educators, and electronics hobbyists to design, test, and verify their circuits virtually before building them.
