Gnucap

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.
