When importing an Early Power Estimator file generated in an Intel® Quartus® Prime Software design project with the following assignment, unused transceiver channels are included in the Intel® Arria® 10 Device Early Power Estimator.
set_global_assignment -name PRESERVE_UNUSED_XCVR_CHANNEL ON
set_instance_assignment -name PRESERVE_UNUSED_XCVR_CHANNEL ON -to <pin_name>
These assignments are used to prevent performance degradation of unused transceiver RX channels over time. For more information about these assignments, see Intel® Arria® 10 Transceiver PHY User Guide.
If you don't need to prevent performance degradation of unused transceiver RX channels and want to remove unused transceiver channels from importing to Early Power Estimator, remove PRESERVE_UNUSED_XCVR_CHANNEL assignment from the .qsf file of your Intel® Quartus® Prime Software design project.
