Horizon EDA

Horizon EDA is an electronic design automation package, meaning it covers the working path an engineer follows from a circuit drawing to a manufacturable printed circuit board. That path includes entering a schematic, associating each symbol with a real component and its footprint, arranging those footprints on a board outline, and routing copper between their pads. The program is written as a single integrated environment rather than a set of loosely joined tools, so the schematic and the board are two views of one design rather than two files kept in step by hand.

Component data is central to this kind of work: a resistor in a schematic is only useful once it is tied to a specific part with known pads and dimensions, and much of the effort in board design is keeping that library consistent across projects.

The package is published by Lukas K. under GPL-3.0-or-later, so the source is available and derivative work inherits the same terms. The build listed here is for Linux; readers on other operating systems should not assume this entry applies to them.
