ProfiCAD is a powerful and user-friendly electrical CAD program for Windows, developed by  from Czech Republic. It is designed to cater to the needs of professionals in the field of electrical engineering and circuit design, and makes creating electrical and electronic diagrams, schematics, control circuit diagrams, and other technical drawings a breeze.

gEDA is a free, open-source and cross-platform (but mainly designed for Linux) EDA project. It provides a mature electronic design solution, including schematic diagram capture, property management, BOM (Bill of Materials) generation, 20 grid tables, analog and digital simulation, and printed circuit board layout (PCB suite, free software application).

DipTrace is a fully-functional circuit design software. It employs an intuitive user interface, supports multiple languages, is simple and easy to use, and has the shortest learning curve on the market and stable performance; supports layered schematic diagram, high-speed and differential routing, in-depth design planning with real-time DRC check, strong compatibility, etc.; and can exchange all data with EAGLE, Altium Designer, PADS and Cadence (OrCAD).

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.

EDA (Electronic Design Automation) refers to delegating various tasks in circuit design to computer to assist in the completion. For example, schematic diagram drawing, printed circuit board file production, implementation of circuit simulation, and so on design works. With the vigorous development of electronic technologies, new components and parts emerge in endlessly, and electronic circuits become more and more complex, the design work of circuits can no longer rely solely on manual work to complete. As a result, computer-aided design for electronic circuits has become an inevitable trend.
