Fritzing is a free (pay to download), open-source electronic design automation software for Windows, Mac and Linux platforms, developed by Interaction Design Lab Potsdam from Germany, using C++. It simplifies what PCB layout engineers did in the past, all using drag & drop method to easily finish complex circuit design.

ELECTRA is a new generation of shape-based and automated routing software for PC boards, developed by KONEKT from Belgium. It can provide high completion rates for automated routing on the most densely populated multi-layer PCB designs. Compared with traditional grid-maze autorouters, the shape-based approach makes more efficient use of routing areas, and is better suited to deal with the complex design rules and requirements of high density SMD or through hole boards, thus achieving the highest routing completion rate.
