Node instance instantiated with unknown parameter

Hello,

I updated the settings of FIFO through MegaWizard and clicked Finish to generate the needed files (including DATA_FIFO_inst.vhd).

https://www.alteraforum.com/forum/attachment.php?attachmentid=8888

The 'DATA_FIFO_inst' is used as a component in anther vhd file (file is attached)

By running the compilation, I am getting the following errors

--- Quote Start ---

Error (12077): Node instance "DATA_FIFO_inst" instantiated with unknown parameter "intended_device_family"

Error (12077): Node instance "DATA_FIFO_inst" instantiated with unknown parameter "lpm_numwords"

Error (12077): Node instance "DATA_FIFO_inst" instantiated with unknown parameter "lpm_showahead"

Error (12077): Node instance "DATA_FIFO_inst" instantiated with unknown parameter "lpm_type"

Error (12077): Node instance "DATA_FIFO_inst" instantiated with unknown parameter "lpm_width"

.

.

--- Quote End ---

Can some body explain to me why? (taking into consideration that the parameters are correct!)

    Hello.....anybody here!

    Is my question really difficult or a stupid question? :)

    Have you solved this? I can't see anything wrong with your code which only makes me think that your project is (perhaps) pointing to the wrong version of the DATA_FIFO source file.

    actually, Altera support were kind and they answer my question.

    They advised me to comment out the GENERIC ( .. ); from line 91-105 and GENERIC MAP (..); line 155-169

    and it works!

    But i did not understand why I should comment them out. I want to include DATA_FIFO to my design, so logically it should be included.
