gEDA Resources

Useful resources for working with gEDA, the GPL'd suite and toolkit of Electronic Design Automation software.

Note 1: This page is a continuing work in progress.

• All about gEDA at Open Circuits

Installing gEDA

Installing gEDA on Windows

• gEDA can be run on Windows natively, as a cygwin application, or in a virtual machine.
• "Official" Windows installers are available here, maintained by DJ Delorie, one of the core gEDA developers.
• In case of difficulty with the latest, "official" versions, there are also unofficial "native" installers available. We would recommend this installer by Peter Clifton.
• Another set of unofficial installers.
• Virtual machine method: Download Virtualbox and download Ubuntu, so that you can run Ubuntu in a virtual machine on your computer. (It's fast and easy!) Then, install gEDA (gschem and PCB) from the Ubuntu software center.

Installing gEDA on Mac

• gEDA can be run on the Mac as an X11 application or in a virtual machine.
• Standard method 1: Use MacPorts, and install both "geda-gaf" and "pcb." You may also want to use the Porticus GUI to make that process easier.
• Standard method 2: Use Fink, and install the "geda-bundle." You may also want to use the Fink Commander GUI to make that process easier. More about this process here.
• Standard method 3: Use Homebrew and "brew install geda-gaf pcb".
• Virtual machine method: Download Virtualbox and download Ubuntu, so that you can run Ubuntu in a virtual machine on your computer. (It's fast and easy!) Then, install gEDA (gschem and PCB) from the Ubuntu software center. Note: this is faster than the Fink method-- under 1 hour, if you have a reasonably fast internet connection.

Installing gEDA on Linux

• In Ubuntu, install gEDA (gschem and PCB) from the Ubuntu software center.
• Similar packages are available for other Linux flavors, for example as Debian Packages.
• Those familiar with git, those keen to contribute to the code base, and those seeking the latest version, should consider building from source under linux, see git.geda-project.org for further details.

Introductory tutorials

• The classic tutorial by Bill Wilson
• Getting started with gEDA 7 MB PDF tutorial, from Cambridge University Engineering Department, covering schematics, layout, and spice
• PCB tutorial (layout only) by DJ Delorie
• Tutorials by Abhijit Kshirsagar
• PCB basics and gEDA/PCB Tips and Tricks -- a forum post at 5 Man Conspiracy

In-depth documentation about gschem and PCB

• gschem user guide at the gEDA wiki
• PCB manual
• PCB Tips at the gEDA wiki. Extremely helpful.

Symbols and Footprints

Symbols: Schematic symbols for use in gschem

• gedasymbols, the largest single repository
• The gedasymbols repository accessible via cvs: time spent learning to checkout a copy of the repository via cvs will be rewarded with a local copy of the gedasymbols content and the ability to share your symbols, footprints and utilities with others
• translate2geda a java utility that will convert .bxl (Vendor neutral format), .ibs, .symdef (gschem utility), .bsd (BSDL), .lbr (Eagle XML format) device descriptions into gEDA gschem and geda PCB compatible footprints (.fp) and symbols (.sym). Gerber files can also be converted into a gEDA PCB footprint with translate2geda.
• BXL2text, a utility to convert manufacturer supplied BXL files; BXL files contain schematic symbols and footprints.
• Symbols by Matt Sarnoff
• Tutorial on creating your own symbols
• KicadSymbolToGEDA a java utility that will let you convert Kicad symbol libraries (.lib) into gEDA gschem compatible symbols (.sym). Kicad is another FOSS PCB design tool. Large repositories of Kicad libraries are available online and by importing existing symbols, quite a lot of time and effort can be saved.

Footprints: component footprints for use in PCB

• gedasymbols, the largest single repository
• Footprints by Matt Sarnoff
• PCB Footprints by John C Luciani -- excellent collection
• Ronja Guidelines - Creating SMD footprints (simple guide)
• translate2geda a java utility that will convert .bxl (Vendor neutral format), .ibs, .symdef (gschem utility), .bsd (BSDL), .lbr (Eagle XML format) into gEDA gschem and PCB compatible footprints (.fp) and symbols (.sym). The translate2geda utility can also convert LT-Spice (.asc) and QUCS (.sch) files into gschem compatible schematic (.sch) files. Gerber files can also be converted into a gEDA PCB footprint with translate2geda which is useful for extracting footprints or modifying legacy designs.
• KicadModuleToGEDA a java utility that will let you convert Kicad legacy modules and the newer s-file modules into gEDA PCB footprints. Kicad is another FOSS PCB design tool.
• BXL2text, a utility to convert manufacturer supplied BXL files; BXL files contain schematic symbols and footprints.
• PDF to PCB footprints via pstoedit.
• Image file to silkscreen footprint elements via a small utility image2footprint

Footprint-generating utilities

• Footgen, Darryl Harmon's python-based footprint generator for geda/pcb
• Ruby-based footprint generator by Stefan Salewski
• Footprintbuilder interactive Java-based footprint design tool supporting gEDA/PCB and KiCad by Robert Fitzsimons
• Browser-based footprint generator
• Browser-based rectangular footprint generator by chlazza.net
• A method of making constraint-based footprints
• FootprintTextForPCB a java utility to turn text into footprint silk line elements
• dxf2pcb a python script that will convert dxf files into either elements for use in footprints, or pcb layout snippets for uses such as defining board outlines and mounting holes, by Gabriel Denk.

• PCB Footprint guide at the gEDA wiki
• Footprint Creation Guide (1.1 MB PDF document)

gEDA Utilities

• Wedana: Cross-platform browser-based tools to view and edit data from gEDA applications.
• A script to convert gschem .sch files to SVG
• Additional fonts for PCB: Hershey single stroke fonts for gEDA PCB, some of which are decorative, as well as Chinese, Japanese and Korean glyphs, as well as Hebrew, Cyrillic and Greek fonts for the intrepid
• Using pstoedit to create silkscreen versions of bitmaps: How to add custom images to the silkscreen layer for gEDA PCB, using pstoedit
• A video tutorial on how to convert .svg and .ps graphics to silkscreen layer artwork using inkscape, pstoedit and a text editor.

Simulating circuits with gEDA and friends

• Beginners tutorial at Ashwith, the first of several
• Tutorial by Stuart Brorson
• translate2geda a java utility that can convert LT-Spice (.asc) and QUCS (.sch)files into gschem compatible schematic (.sch) files. This is useful for those who use LT-Spice or QUCS for circuit modelling, but lay out designs for manufacture in gschem +/- gEDA PCB, or require gschem to produce schematics suitable for publishing. Simulator compatible symbols in the repository need to be added to gschem's local default symbol library.
• ltc2pcb a utility for importing LT-Spice netlists into gEDA PCB.
