[PLUG] circuit design and simulation software

[tim at wescottdesign.com]

It depends on how committed you are to open source.  The more or less  
industry standard, unless you're doing really serious big circuits, is  
LTSpice.  It's free-as-in-beer, not open-source, and to add insult to  
injury it's a Windows program.

But -- they've taken pains to keep it Wine compatible, and the only  
blatently commercial aspect of it is that the only parts that come  
pre-defined are Linear Technology ones (although Linear's been bought  
by Analog, so things may change).

There are open-source simulation tools out there, but they've been  
overshadowed by LTSpice, and frankly, I haven't used them.

When you start actually laying out boards, KiCad is pure open-source  
way to go.
