Gnucap is a general purpose circuit simulator aimed at analysing and simulating electronic circuits. It supports both analog and digital simulation, allowing engineers, researchers, and students to experiment with circuit designs and evaluate behaviour under different conditions.
The software is designed to be interactive and command-driven, enabling rapid iteration during circuit design. It also supports batch operation and offers compatibility with many SPICE models, making it a practical tool for both learning and professional electronic design workflows.
This is free and open source software.
Key Features
- General purpose circuit simulator for analog and digital electronics.
- Supports nonlinear DC, transient, Fourier, and AC analyses.
- Interactive command-driven interface for rapid design iteration.
- Batch mode and server operation for automated workflows.
- Compatibility with SPICE models including MOSFETs, BJTs, and diodes.
- Mixed-signal simulation with support for both analog and digital components.
