warning 18584 There are no transceivers channels used in the design

Hi,

I have an Arria 10 (10AX027H4F34E3SG)

PC: Windows 10

- Quartus standard 20.1.10.711

-Quartus Pro 21.1.0.169

In both softwares, I get similar warnings:

Warning (18584): There are no transceiver channels used in the design. You must use or instantiate atleast 1 transceiver channel to preserve the rest of unused channels.

Critical Warning (17951): There are 24 unused RX channels in the design. If you intend to use any of these channels in the future, you must add the assignment 'set_instance_assignment -name PRESERVE_UNUSED_XCVR_CHANNEL ON -to <pin_name>' in your QSF file. This assignment will preserve the performance of specified channels over time. Note that unused channel preservation only works if the design uses or instantiates atleast 1 transceiver channel.

I modified the .qsf file with the following:

set_instance_assignment -name PRESERVE_UNUSED_XCVR_CHANNEL ON -to AL30

and other transceiver lines

But in the pro version, I get an error during the compilation:

Error(17950): Pin corresponding to CLKUSR has not been reserved in the device. Cannot perform unused RX clock workaround.

I followed the suggestion:

but I still get the same compilation error. What am I missing?

Cheers
