Gnucap is designed so it can eventually replace Spice. Today, it can replace Spice in some applications. There are some significant technical advantages. It is a work in progress. New features are added regularly as time and demand permits.gnucap:chat2024-02-28T05:41:13-05:002024-02-28T05:41:13-05:002024-02-28T05:41:13-05:00http://gnucap.org/dokuwiki/doku.php/gnucap:chat?rev=1709120473&do=diffThere is a chat on matrix, #gnucap:matrix.org.

Here's how to build your own. Tested on Ubuntu 20.04.
Run these with root privileges.
# apt-get build-dep gnucap
# apt install dpkg-dev fakeroot
These better run without root privileges.
$ git clone https://salsa.debian.org/electronics-team/Gnucap/gnucap
$ cd gnucap
$ dpkg-buildpackage -rfakeroot --no-sign -d
$ ls ../*gnucap*deb
The -d flag was necessary because debhelper-compat (=13) is not available for Ubuntu 20.04.

Build and Install
Gnucap source code is organised as a main library with plugins developped in numerous git repositories.
Plugins and extensions not shipped with the main “Gnucap” package require a Gnucap
installation for compilation and use. Installation instructions can be found in the INSTALL file at the top level of the source repository, and in the respective documentation of the extension packages. Beware of out-of-date binary packages distributed elsewhere.

Within the next months, we will work on two tasks. One task is a compiler for behavioural models, the other is Verilog support on the simulator level.gnucap:packaging2024-02-21T05:16:28-05:002024-02-21T05:16:28-05:002024-02-21T05:16:28-05:00http://gnucap.org/dokuwiki/doku.php/gnucap:packaging?rev=1708514188&do=diff* arch linux

Most of them involve creating plugins. All of them create something that is identifiably yours, that will be noticed. Most of them will stretch your skills a bit. If you want to learn about simulation, beyond what you can get at school, this is the place.gnucap:spectre2008-01-29T20:06:07-05:002008-01-29T20:06:07-05:002008-01-29T20:06:07-05:00http://gnucap.org/dokuwiki/doku.php/gnucap:spectre?rev=1201658767&do=diffThe Spectre language plugin attempts to support the syntax of the Cadence Spectre simulator.
Not all features of Spectre are supported, but those that work will work with Spectre syntax. Wherever possible, Gnucap features will work in Spectre mode, even if they don't work in Spectre.gnucap:start2026-03-23T03:54:46-05:002026-03-23T03:54:46-05:002026-03-23T03:54:46-05:00http://gnucap.org/dokuwiki/doku.php/gnucap:start?rev=1774256086&do=diffGnucap is the GNU Circuit Analysis Package
Gnucap is a modern post-spice circuit simulator with several advantages over Spice derivatives. Gnucap and Modelgen-Verilog support a reasonable subset of Verilog-A, for both structural and behavioural analog/mixed models. Work towards Verilog-AMS with NLnet funding is ongoing.gnucap:user2012-04-27T01:31:40-05:002012-04-27T01:31:40-05:002012-04-27T01:31:40-05:00http://gnucap.org/dokuwiki/doku.php/gnucap:user?rev=1335508300&do=diff--- Savant Krishna 2012/03/31 09:59 --- Savant Krishna 2012/03/31 09:59
