Why does the SDI II IP Design Example fail to generate pathological patterns? - Why does the SDI II IP Design Example fail to generate pathological patterns? Description Due to a problem in the Quartus® Prime Pro Edition Software version 25.3 and earlier, you may observe the high bit-error rates on recovered data when receiving 12G SDI pathological patterns on Agilex™ 7 - F-Tile PMA/FEC Direct PHY FPGA IP Agilex™ 5 - GTS PMA/FEC Direct PHY IP Resolution This problem is scheduled to be fixed in a future release of the Quartus® Prime Pro Edition Software. Once the fix has been implemented in the future release of the Quartus® Prime Pro Edition software, you should be able to select the RX adaptation mode from the native adaptation mode in the Agilex™ 7 - F-Tile PMA/FEC Direct PHY FPGA IP Agilex™ 5 - GTS PMA/FEC Direct PHY IP With this implementation, you can reliably drive the 12G SDI link with up to 15dB of total insertion loss, as validated and quantified from the output of the re-timer to the Agilex™ 7/5 FPGA receiver input. You should ensure the selected re-timer is capable of compensating up to 8dB of channel loss with pre/de-emphasis.
