Build Gnucap with foreign build systems Building a program boils down to compiling binaries from source code using a compiler. However, an large number of “build systems” has been invented for the purpose of invoking a compiler and managing the data. Such build systems are necessarily bound to tradeoffs between simplicity and fancyness driven by both taste and policies. Good tradeoffs do not seem to exist yet. The high number of different implementations displays the lack of agreement on best p…

Gnucap commands are defined by plugins. This section defines all commands supplied in the main tarball. Your installation may not have all of these commands, and may have others in addition to these. It depends on which plugins you have installed.

This section documents compatibility issues, including syntax and feature differences compared to other simulators. In some cases, a workaround is suggested. In almost all cases, there are plans to provide exact compatibility in the future, e.g. with spice.

Gnucap devices are defined by plugins. This section defines all commands supplied in the main tarball, and also the optional “models” tarballs. Your installation may not have all of these, and may have others in addition to these. It depends on which plugins you have installed.

What is it? (taken from 2006 pdf, needs update) Gnucap is a general purpose mixed analog and digital circuit simulator. It performs nonlinear dc and transient analyses, fourier analysis, and ac analysis linearized at an operating point. It is fully interactive and command driven. It can also be run in batch mode. The output is produced as it simulates. Spice compatible models for the MOSFET (levels 1-7) and diode are included in this release. Since it is fully interactive, it is possible to mak…

By use of plugins, Gnucap gives you a choice of simulation languages. The following are the simulation languages supported in this release. Verilog Spectre Spice ACS

Modelgen implements the translation of compact device models to code that can be compiled into a plugin and loaded by the simulator. The traditional version that is currently included with Gnucap reads .model files and writes Gnucap plugins in C++. The version currently under development, Modelgen-Verilog, reads a growing subset of Verilog-AMS, a standardised modelling language.
