Scheme seems to be used extensively.  In particular, check out symsync
http://www.swiss.ai.mit.edu/~jaffer/SIMSYNCH.html

It doesn't require real scheme programming to use, and it is based on scm
which is supposed to be one of those schemes that just work on real platforms.
So far I've only used SCM on linux (I use it at school since I was able
to fit it into my measely account) though.

BTW, the symsynch manual doesn't appear properly in xpdf, but it does appear
fine in gv (some ghostscript front end).

I haven't used this program much.  It is aimed higher than anything I've tried 
to design (which I usually just code up myself when I want to simulate it).  
It is used to do real work though, so it might work for you.
