Cyclone 10 GX - Critical warning for unused XCVR channels
Hello,
In Cyclone 10 GX, Quartus Prime Pro 22.4, I get critical warnings for unused XCVR RX and TX pins.
Critical Warning(17951): There are 4 unused RX channels in the design.
Info(19540): Add the QSF assignment 'set_instance_assignment -name PRESERVE_UNUSED_XCVR_CHANNEL ON -to <pin_name>' for each unused channel that will be used in future.
Info(19541): The above QSF assignment will preserve the performance of specified channels over time, and works only if the design uses at least 1 transceiver channel.
Critical Warning(18655): There are 4 unused TX channels in the design.
Info(19540): Add the QSF assignment 'set_instance_assignment -name PRESERVE_UNUSED_XCVR_CHANNEL ON -to <pin_name>' for each unused channel that will be used in future.
Info(19541): The above QSF assignment will preserve the performance of specified channels over time, and works only if the design uses at least 1 transceiver channel.
I'm making the suggested .qsf assignments, however the critical warnings persist. Is there another way to disable the warnings?
Regards,
Frank
Hello,
I found the solution by inspecting the configuration of Cyclone 10GX Devkit example project. The expected setting is
set_global_assignment -name PRESERVE_UNUSED_XCVR_CHANNEL ON
rather than multiple
set_global_assignment -name PRESERVE_UNUSED_XCVR_CHANNEL ON -to <pin_name>
