Hi Ahmed,

I can tell you what was the problem with my appliation- I hope it will be relevant to yours.

The altera IP generator creates different files. One of these files has the ".ipx" extension. If, for some reason, a Quartus project that uses the IP cannot find a file with that extension (.ipx) Quartus will give the following error message:

(Error: IP Generator Error: Entity '' (Version latest) not found in librarian.)

I personaly think this message is misleading, and I have spent quite some time before finding the answer. I wrote in my previous message that I think they should do something about this error message but appearently Altera does not feel the same (or nobody there knows about this problem).

I can also say that I saw this error message when there was a difference between the two versions (for example: using Quartus 7.2 with IP core 6.1). It happend on and old version and I do not not if this still applies now.

I hope I helped a little

Godd luck,

Gilad
