Tanner's tools are really nice, he's got a nice niche with Windows safe
from the other CAD gods.  It does relegate the tools to toy designs, at
least it did when we were trying to use his simulator in the early 90's
to build the Message Driven Processor.  The simulator itself was fine,
but Windows was not suitable for large IO, memory, and so on.

Magic is nice, but the GUI is slight beyond the border outside being
tolerable for an undergraduate VLSI student to use.  It's not a Linux
thing - the Gnome interface is nicer than Windows.  Magic's not
supporting schematics is maybe a feature, but the interface from Magic
layout to SPICE is abysmal, and it's embarrassing to teach using irsim.

So I'd rather teach the students using Tanner. It doesn't matter if
Windows is world class these days, because students are still doing toy
designs.  Tanner's also got a nifty MEMS suite. 

However,  Windows is not a viable platform for education because I can't
remotely administer the installation, check student designs to
correspond with them when I'm off campus.  I've learned the hard way at
my office that administering windows systems is an endless time sink of
registry problems, disappearing drivers, weird crashes, and so on. 
While Linux boxes stay up for months or years without being touched.

Maybe the next generation Tanner will be written in Java.
