Cyclone 10 GX - Critical warning for unused XCVR channels - 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?

Best regards, Zi Ying Replies: Re: Cyclone 10 GX - Critical warning for unused XCVR channels 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> Regards, Frank
