FreePCB -- free tool for PCB design & editing on Windows-based PCs.
Why should circuits have all the fun when it comes to free design software? Where is the love for PCBs -- and the free software tools for design and editing? The answer is they do, in the form of FreePCB, which allows users to design and edit PCB schematics using a simple graphical interface. The interface won't win any awards for the 2D graphics themselves, however its 'beauty' lies in its functionality. Users are able to design PCBs with up to 16 copper layers at a maximum size of 60 X 60-inches! To put that into perspective, that's a 5-foot square motherboard! The software suite provides the all the tools needed for PCB layouts, including English and metric functions, Ivex Design International, PCB Matrix and IPC libraries. FreePCB also comes with Footprint Wizard/Footprint Editor 
for footprint design and editing, design rule checker and the ability to import and export PADS-PCB netlists. The software is designed to work under Windows, however it can run on Mac and Linux-based systems using Virtual Box or Wine through the MacPorts application.

Thanks for the great article. Here are 12 more free software tools for Engineers.

 

Math Tools:

1 - SciLab - Another incredibly powerful and flexible alternative to MatLab

2 - Maxima - Another great & free math package

PCB Layout and circuit simulation

3- KiCad - A completely free circuit schematic and PCB layout tool

4-ngspice - A completely free SPICE cli-based circuit simulation tool

5-LTspice - Another free graphical SPICE simulator

 Embedded/Software development:

6 - Eclipse - An incredibly powerful  IDE with a multiude of plugins that enable it to be used from everything from Embedded to Web Development

7 - GCC - One of the most well known C/C++ compilers available for many archtectures and flavors

8- OpenOCD - An incredibly flexible on chip debug tool that cann be used to program & debug many embedded devices/ microcontrollers. 

9-GNU Make/Autotools - A powerful build system for building all sorts of software projects

10 - CMake - Another powerful build system 

Documentation:

11- PanDoc -  An awesome documentation tool capable of converting markdown to HTML or PDF. It also converts to/from Latex

In the article number 7. The author wrote this app is free but it is not.

For viewing Gerber files I recommend GC-Prevue from www.graphicode.com.  It is a free Gerber file viewer.  They also have other more-capable purchasable tools.

Add QUCS to the Free Design Tools

Quite Universal Circuit Simulator (QUCS) is a great little Spice-like open-source tool that runs quickly, has a wide range of components, rather intuitie interface (but a so-so manual), and will execute S-parameter analysis. Available at qucs.sourceforge.net/.

I've used Eureqa by www.nutonian.com, sounds similar.  There's a useful but limited free version.

I have tried FreePCB couple of times, it is not bad for most projects with 16 layers or less. Some features I wish it had are viewing Gerber files, import/export of DXF files and print capability!

What is the basis of this ranking?

Is this ranking based on a survey of engineers? If so, what is the size of the sample and how was the sample chosen?

:-)  Yes, it can be a rare commodity when engineers interact with non-engineers!  Oh, well, c'est la vie!

I cannot disagree.  I suppose I've been lucky a lot of the time; I usually have the opportunity to insist that things are done properly.  I don't take that for granted. ;)
