PLL compilation error

Hi

I have got an error on the PLL during compilation. I have seen this error a couple of times before, but I have never figured out what the problem is.

The project is a reference design which should work.

It seems like the compiler cannot find the design files for the PLL. I believe that I have included all the standard folders.

Does anybody know how to fix the error?

Thanks

Tom

    Quartus II search for source file into the following order:

    - into the list of files that you have explicitely add to your project; see menu Project => Add/Remove Files in Project...

    >>> if it does not find the file

    - into the project folder

    >>> if it does not find the file

    - into the folder that you have specify as Libraries; see menu Assignment => Settings => Librairies

    So in your specific case, it gives a warning just to alarm you that the file it found was not specified as a design file and read by default the one that it found into the Quartus II project.

    I met this problem too.

    I found the "altpllpll.v" file has not avaliable code in it.

    And when I goto the SOPC Builder, I can not modify the pll component.

    I clicked the "Launch Altera's ALTPLL MegaWizard" button, but nothing happened, the configuration dialog box never show up.

    But, when I change to another project , the SOPC and PLL works fine!

    I'm stuck here too.
