Error(129001): Input port CLK on atom "ALTDDIO_OUT_component|auto_generated|ddio_outa[0]", which is a twentynm_ddio_out primitive, is not legally connected and/or configured


You may see this error when compiling a design containing an instantiation of an altddio_out or altddio_in primitive targeting the Intel® Arria® 10, Intel Cyclone® 10GX or Intel Stratix® 10 device family.


This error occurs as the altddio_out and altddio_in primitives are not intended for use with these device families.

Use the Altera GPIO IP Core instead of the altddio_out and altddio_in primitives for the Intel Arria 10, Intel Cyclone 10GX or Intel Stratix 10 device families.
