Custom component with GPIO Lite component generates 12006 error: undefined entity

Try adding the Qip file in the project add/remove section. I have had this issue before as well when using the FFT core. I solved it by adding the Qip in the overall project section in quartus. Hope this helps..

Hello!

I've created a custom component in Qsys that includes a Altera GPIO lite component. The component is instansiated like this:

    inst_lvds_input : LVDS_INPUT
    PORT MAP
    (
        dout            => reg_lvds_in,
        pad_in(0)          => lvds_in_pos,
        pad_in_b(0)     => lvds_in_neg
   );

The component is then copied to the IP folder of another Quartus project and included into a Nios system. Qsys creates the system but when running the synthesis in Quartus the error message is:

Error (12006): Node instance "lvds_input_inst" instantiates undefined entity "altera_gpio_lite". Make sure that the required user library paths are specified correctly. If the project contains EDIF Input Files (.edf), make sure that you specified the EDA synthesis tool settings correctly. Otherwise, define the specified entity or change the calling entity. The Altera Knowledge Database contains many articles with specific details on how to resolve this error. Visit the Knowledge Database at https://www.altera.com/support/support-resources/knowledge-base/search.html and search for this specific error message number.

I've included the .qip file into my custom component in Qsys but didn't seem to make a difference as it shows up in the synthesis folder of the new Nios system.

Any ideas?
