Why does the F-Tile Triple-Speed Ethernet IP with core variation 10/100/1000 Ethernet MAC with 1000BASE-X/SGMII 2XTBI PCS and Embedded PMA Signals (F-Tile) drop packets? - Why does the F-Tile Triple-Speed Ethernet IP with core variation 10/100/1000 Ethernet MAC with 1000BASE-X/SGMII 2XTBI PCS and Embedded PMA Signals (F-Tile) drop packets? Description Due to a problem in the Quartus® Prime Pro Edition Software version 25.1.1, you may see packets dropped when the F-Tile Triple-Speed Ethernet IP is configured to 10/100/1000 Ethernet MAC with 1000BASE-X/SGMII 2XTBI PCS and Embedded PMA Signals (F-Tile) variant. This is because the IP default settings for flux_mode are set as " FLUX_MODE_FLUX_MODE_SNIFFER " and rx_adaptation_mode is set as " RX_ADAPTATION_MODE_FLUX_ADAPTATION ". Since the F-Tile Triple-Speed Ethernet IP line rate is 1.25 Gbps, the recommended flux_mode needs to be set as " FLUX_MODE_FLUX_MODE_BYPASS " and rx_adaptation_mode needs to be set as " RX_ADAPTATION_MODE_MANUAL_ADAPTATION ". Resolution To work around the above problem, you can add the following assignment to the project setting .qsf file: set_instance_assignment -name HSSI_PARAMETER "flux_mode=FLUX_MODE_FLUX_MODE_BYPASS" -to <RX_SERIAL_PIN> -entity <TOP_LEVEL_NAME> set_instance_assignment -name HSSI_PARAMETER "rx_adaptation_mode=RX_ADAPTATION_MODE_MANUAL_ADAPTATION" -to <RX_SERIAL_PIN> -entity <TOP_LEVEL_NAME> This problem is scheduled to be fixed in a future release of the Quartus® Prime Pro Edition Software.
