Solution
These messages typically appear if you compile a reference design for the first time without
generating the EtherCAT IP Core first. The errors occur because important library files need to be
copied to the project folder. Open MegaWizard Plug-
In for the EtherCAT IP Core and press “Finish”
(refer to the datasheet: reference design/implementation chapter). Quartus II will copy the required
files to the project folder. Compile the project again, the error messages should disappear.
