For IP shopping lists you are better off trying on opencores.org, maybe there's something you can use. And that "better off" is purely a relative measure.

But hey, at least it's not pre-alpha. XD

Its free of charge ... or you can pay it and you will get release version :-D

Heheh, fair enough. I guess my beef with opencores isn't so much the monetary cost, because as you point out it's free. Buuuut so far whenever I needed some functionality, and there was something that was a close enough match to try it ... invariably it sucked pretty bad. But hey, it was free, so I cannot complain to the author. All I can do is learn that for the stuff I need opencores is not the location to find solutions.

Ive never used anything off opencores mainly for its reputation for poor code and incomplete designs, with uncontactable authors. But when you work for a company you have the luxury of buying a core from a company via a contract, so there is some come back if it doesnt work.
