GNU Octave for high-level interpreted language numerical computations
Another popular free mathematical tool comes in the form of GNU Octave, which is intended for numerical computations like those needed for chemical engineering and scientific computing. The software platform is a conglomerate of tools designed to solve numerical linear algebra problems, getting to the 'root' of non-linear equations and integrating ordinary functions. The fun doesn't stop there, as Octave also incorporates tools for manipulating polynomials as well as integrating ordinary differential and differential-algebraic equations. As with most great open-source software, Octave can be modified and redistributed by its users using any number of languages, including C, C++ and FORTRAN among a host of others.

ICircuit is not Free

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. ;)

Not disputing that.  But time is a constraint that must also be accommodated...and meeting the schedule is not always "not good engineering." 

 

I think we have to meet in the middle here.
