KiCad

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 materials list, and PCB layout. Description-Source: Wikipedia

Features:

• 3d renderer
• 3d sketching
• Wast library

Autodesk EAGLE

* Quickly test your ideas and validate circuit performance with a complete suite of SPICE simulation methods. * Drag-and-drop reusable design blocks between your projects, complete with synchronized schematic and PCB circuitry. * Precisely arrange and order PCB design objects with a complete set of alignment tools. * Route complex PCB layouts and maneuver around your design to easily get your trace to its destination. * Don’t rely on luck to fit your board in its enclosure.

LibrePCB

Cross-platform (Unix/Linux, Mac OS X, Windows) All-in-one (project management, library/schematic/board editors) Intuitive, modern and easy-to-use graphical user interface Very powerful library design with some innovative concepts Human-readable file formats Open Source (GNU GPLv3)

iCircuit

Its advanced simulation engine can handle both analog and digital circuits and features realtime always-on analysis. It is the perfect companion to students, hobbyists, and engineers. You use it as you would any CAD program: you add elements, connect them together, and set their properties. But iCircuit is unlike other CAD programs because it is always simulating. It's just like working with the real circuit. You do not stop to take a measurement or spend a lot of time configuring reports.
