There was an article in EDN magazine several months ago listing availability
and mini-reviews of "free and inexpensive" PLD software.  Turns out that a
failry large number of the software packages given away to sell some vendor's
neat new high density chip will also still do "generic" devices like the
16V8, 22V10, and so on.  You might be able to find the article somewhere
on www.ednmag.com.
