KiCad is an open source software suite for electronic design automation (EDA) - designing schematics of electronic circuits and printed circuit boards (PCB). KiCad is developed by Jean-Pierre Charras. And features an integrated environment between schematic capture, bill of...

Fritzing is a very-very handy a tool, very complex but very simple to use, to design circuits, as well as so called "layouts", be it PCB or stripboard or breadboard.

Square Sketch recreates drawing and writing on graph paper. Instead of a pen, a mouse and keyboard are used, creating precise vector graphics that can be edited flexibly.

Schematic capture, Ngspice based simulation, PCB layout, custom PCB manufacturing, for electronic engineers, educators, students and hobbyists.

Autodesk EAGLE is an electronic design automation (EDA) software. Enabling printed circuit board (PCB) designers to seamlessly connect schematic diagrams, component placement, PCB routing, and comprehensive library content.

Proteus PCB design combines the schematic capture and ARES PCB layout programs to provide a powerful, integrated and easy to use suite of tools for professional PCB Design.

LibrePCB is a free EDA software to develop printed circuit boards. It’s currently under heavy development to bring out first stable releases as soon as possible.

Altium Designer software is for PCB design. From schematic capture to PCB design as well as FPGA Programmation, signal integrity check, mixed analog/digital simulation, this software is what you need when it comes to PCB design and all aspects of ECAD/ MCAD and team...

NI Circuit Design Suite software improves the PCB design process by integrating capture, simulation, and layout into a single toolchain with NI Multisim and Ultiboard software.

This electronic circuit simulator is highly interactive giving the feeling of playing with real components. It's very helpful for experimentation and visualization. It's a desktop version of the Circuit JS.

The 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.

The Cadence OrCAD product line provides affordable, high-performance PCB design tools that boost productivity for smaller design teams and individual PCB designers.
