Oh yeah, RHDL ;-)  Like I said in my previous post, I've got to work on 
some better RHDL docs (maybe over spring break).  Competition is always a 
good motivator :)

I don't know about PyCudd, but I've got it working with Ruby (RuCudd?) - 
wrapped it using Swig.  If you're interested let me know and I could send 
you the .i files for swig. (NOTE: it's not 100% complete, but very usable 
at this point).
