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.

gEDA Project

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.

Autodesk Tinkercad

Tinkercad is a super easy-to-use, browser based 3D design tool. With Tinkercad you can create 3D printable items: toys to play with, decoration to light up your home or jewelry to express yourself. You dream it, you can make it!

Features:

• 3D modelling
• Browser based
• Web-Based

EasyEDA

EasyEDA is a cloud-based EDA tool suite which supports open source and working collaboratively. A full suite schematic and PCB design software/manufacturing service that’s free to use and offers great prices on custom PCB manufacturing. All files in open format JSON. Can import Altium, Eagle schematics and also LTspice schematics for (limited) simulation and for conversion to PCB with full BoM support. Spice netlist import and export. Altium, PADS and Free PCB netlist export.

NI Circuit Design Suite Power Pro

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. Multisim easily captures schematics that are immediately ready to be simulated.

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)

OrCAD (All Products)

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

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.

Features:

• Price alerts
• Simulation
