The GPL Electronic Design Automation (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/gaf suite (this package) provides schematic capture,
netlisting, bill of materials generation, and many other features.
