Why are unused transceiver channels included in Intel® Arria® 10 Device Early Power Estimator when an Early Power Estimator file is imported from an Intel® Quartus® Prime Software design project? - Why are unused transceiver channels included in Intel® Arria® 10 Device Early Power Estimator when an Early Power Estimator file is imported from an Intel® Quartus® Prime Software design project? Description 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. Resolution 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.
