GNU Circuit Analysis Package
@Gnucap

Gnucap is a modern “post-spice” analog and mixed signal circuit simulator.

We aim to build a modular next generation circuit simulator that integrates well with existing platforms, supports standards and brings modern algorithms into applications.

Gnucap integrates well with the graphical user interface from the Qucs project and provides Python bindings for unlimited scripting and interoperability.

See http://gnucap.org/dokuwiki/doku.php/gnucap:start for technical details.
