Gerber Viewer is a viewer for Gerber files, also called RS274X. It lets you load several files on top of each other, do measurements on the displayed image, etc. Using Cairo makes it possible to export Postscript and PDF files.

Signs is a development environment for hardware designs in various hardware description languages. The tackled tasks are compilation, synthesis, simulation, and testing of designs. Due to the integration of these main areas, it provides the ability to debug designs in an all-embracing manner by switching between source code, netlist, and simulation. Supported languages include VHDL and the ISCAS benchmark format. Signs comes in two flavors: a command-line only version useful for processing and analyzing large netlists and as an Eclipse plugin for hardware design and simulation.

KiCad EDA is software for the creation of electronic schematic diagrams and printed circuit board artwork. It is a set of four programs and a project manager: Eeschema (schematic entry), Pcbnew (a board editor), Gerbview (a Gerber viewer (photoplotter documents)), and Cvpcb (a footprint selector for components used in the circuit design). Kicad is the project manager. It includes a 3D visualization feature.

BeRTOS is a real time operating system (RTOS) suitable for embedded platforms. It runs on many microprocessors and microcontrollers, ranging from 8-bit to 32-bit CPUs and even PCs.

Gaphor is a UML modeling tool written in Python (2.2). It utilizes the GTK+ widget library, and is designed to be very extensible.

GTKWave is a wave viewer for Verilog simulation. The viewer supports execution of Tcl scripts and enhanced Drag and Drop operations.

Qfsm is a graphical editor for easily drawing finite state machines, written in C++ using Qt. Transitions can have either binary or ASCII conditions. Machines can be simulated and integrity checks applied, enabling verification of proper design and operation.

TkGate is an event-driven digital circuit simulator with a TCL/Tk-based graphical editor. It supports a wide range of primitive circuit elements and user-defined modules for hierarchical design. The distribution comes with a number of tutorial and example circuits which can be loaded through the "Help" menu, and the example circuits include a simple CPU, programmed to run the Animals game. TkGate has multi-lingual support for English, Japanese, French, German, Spanish, Welsh, and Catalan.

Oregano is an application for schematic capture and simulation of electrical circuits. The actual simulation is performed by SPICE, which is required for simulation, but not necessary to run the application.

iBookshelf is an application for cataloging your book collection and designing bookshelves based on this data. It supports ISBN entry using a CueCat, a standard barcode scanner, or manual entry. Book data is automatically fetched from Amazon Web services. Manual book entry is possible for non-catalogued books. Bookshelf design is done graphically with the Cairo drawing library, and is based on the most efficient book order.

Ngspice is a mixed-level/mixed-signal circuit simulator based on three open source software packages: Spice3f5, Cider1b1, and Xspice. Spice3 is the most famous and widely used circuit simulator. Cider is mixed-level simulator that includes Spice3f5 and adds DSIM, a device simulator. Cider couples the circuit level simulator to the device simulator to provide greater simulation accuracy (at the expense of greater simulation time). Xspice is an extension to Spice3 that provides code modeling support and simulation of digital components through an embedded event driven algorithm.
