The gEDA project has produced and continues working on a full GPL'd suite and toolkit of Electronic Design Automation tools. These tools are used for electrical circuit design, schematic capture, simulation, prototyping, and production. Currently, the gEDA project offers a mature suite of free software applications for electronics design, including schematic capture, attribute management, bill of materials (BOM) generation, netlisting into over 20 netlist formats, analog and digital simulation, and printed circuit board (PCB) layout.

The gEDA project was started because of the lack of free EDA tools for POSIX systems with the primary purpose of advancing the state of free hardware or open source hardware. The suite is mainly being developed on the GNU/Linux platform with some development effort going into making sure the tools run on other platforms as well.

1. gEDA: gSchem
Удобная программа для проектирования схем

Описание (eng):
gschem is the schematic capture program/tool which is part of gEDA. It’s sole purpose is to facilitate the graphical input of components/circuits.
gnetlist is a netlist generation program. It takes as input gEDA/gaf .sch (schematic) file and the required .sym (symbol) files and converts them into netlists.
gattrib is gEDA’s attribute editor. It reads a set of gschem .sch files (schematic files), and creates a spreadsheet showing all components in rows, with the associated component attributes listed in the columns.
symbols (on a schematic) are an abstract representation of the physical components used in electronic circuits.
There are many utilities included as part of gEDA/gaf.
gsymcheck is the symbol checker for the gEDA/gaf system. Give it a symbol file and it will go through and verify that the symbol will work in gschem and friends.

2. gEDA: PCB
Очень удобная утилиты для проектирования печатных плат
(PS: осторожней с печатью, у меня в первый раз вылетело 12 страниц)

Описаие (Eng):
PCB is an interactive printed circuit board editor for the X11 window system. PCB includes a rats nest feature, design rule checking, and can provide industry standard RS-274-X (Gerber), NC drill, and centroid data (X-Y data) output for use in the board fabrication and assembly process. PCB offers high end features such as an autorouter and trace optimizer which can tremendously reduce layout time.

0. gEDA: Gerbv
Утилита для просмотра файлов первых двух программ

Описание (Eng):
Gerber files are typically output by a PCB CAD tool (such as the gEDA Project's PCB), and are sent to a PCB manufacturer who uses the files for manufacturing Printed Circuit Boards (PCBs).

There are two standards defining Gerber files: An old one called RS-274D, and a newer one called RS-274X. Gerber files generated in the old format (RS-274D) lack aperture information, which must be supplied separately. The new standard (RS-274X) embeds aperture information into the file. Note: Gerbv displays RS-274X files! Gerbv will not display RS-274D files! When you create Gerber files using your PCB tool make sure you export RS-274X files if you want to view the files with gerbv.

In the Gerber format, the different layers of a PCB (e.g. top silk, top metal, interior layers, etc.) are held in separate files. Information about the PCB's stackup (i.e. layer order, thickness, etc) is not captured by Gerber files; it is up to the user to supply this information to gerbv, and to his PCB manufacturer.
