Hello!
What element should be connected to the output of
altddio_out so, that it will be possible to connect the output of
altddio_out to any element in the schematic ( . bdf )?
If I connect the output of
altddio_out directly to any element in the schematic ( . bdf ), then Quartus qives out an error:
Error (15873): Output port DATAOUT of DDIO_OUT primitive "aes_output:inst9|altddio_out:altddio_out_component|ddio_out_2ad:auto_generated|ddio_outa[0]" must drive input port I of an I/O OBUF primitive
But where can I find
i/o obuf primitive ?
I coudn't find it , instead I found
alt_outbuf, but using it instead of
i/o obuf also resuts in Quartus errors.

Is there a synthesis setting to stop IO buffers being inserted (for when you're black boxing a pieve of code) that is accidentally enabled?
Nial.
