SDB's gEDA stuff

gEDA is a GPL'ed EDA environment for Linux. It includes a great schematic capture package, a netlister which outputs SPICE and other netlist formats, and a bunch of utilities. Associated with gEDA are several other electronic design tools, including ngspice -- an open source SPICE3f5 simulator.

I actively use the gEDA toolset for my own work. I also have made contributions to the various projects. Links to my contributions are listed below.

• SPICE stuff, including the improved spice netlister spice-sdb. This page also has patches to the schematic capture utility gschem and the netlister gnetlist.
• A SPICE/Linux HOWTO in .pdf and Docbook format. I submitted this HOWTO to the Linux Documentation Project, but the application seems to have gone dormant. The text is derived from my SPICE on gEDA on Linux HOWTO which is available as a set of web pages under my SPICE on Linux resources webpage. I have made some changes and improvements to the exposatory text for the HOWTO. However, it is still a work in progress.
• Gattrib -- a spreadsheet-style attribute editor for gEDA written in C. It is useful for managing component and net attributes in large designs.
Garchive -- a project archiver utility for gEDA written in Python. ->
• Various throw-away Utilities for gschem and gEDA.
• A drawing of the data structures used in libgeda -- This shows how your schematic is represented by the TOPLEVEL data structure defined in libgeda/includes/struct.h.
• smtgen.pl A Perl script which generates PCB footprints for two pad SMT mount parts such as 0805 and 1206 passives. Example usage:
  perl smtgen.pl -v l=85 w=55 g=32 x=38 y=59 description=SMD_Res_0805
  More information about its usage is available by saying "perl smtgen --help" or inspecting the source code.
• A Document about creating footprints for the open-source PCB layout program called "PCB". This document explains how to create a "newlib" footprint. The document is available in either PDF form (land_patterns_20070805.pdf) or in Open Office .sxw format (land_patterns_20070805.sxw). The latest version is date-coded 20070805.
• A simple start-to-finish PCB project done with the gEDA Suite -- ProximitySensor.tar.gz. This tarball holds the entire project directory; you can use it as a template or example showing how to configure your own project directory when doing board designs using gEDA.
• libgeda_functions.sxw: the beginnings of a document describing the functions (algorithms, calling args and return value) held in libgeda: I started this doc to help myself while writing gattrib. It is woefully incomplete, but can serve as a starting point for anybody who wants to work on it. I will happily accept and and all useful patches to the doc, and will keep it updated as the waves of patches flow in! It was created using OOO's Writer.
• A Gnumeric spreadsheet used for computing the noise expected from a photodiode transimpedance amplifier. The spreadsheet is the front end where the user can input all required parameters. The back end is a Python program which computes all the required integrals.
