HDL designer and altera megafunctions

Hello guys,

Does anybody know how to use the altera's megafunction with the hdl designer software ??

I have imported the precompiled altera's library located in the modelsim-altera folder

I have run the megafunction plugin in HDL designer and now I can see the megafunction entity in my project library

By the way when I instantiate it in my topdesign and run the design checker I get several errors.

Any suggestions ?
