Why don’t I see some HSSI analog parameters value set in the GTS PMA registers when these values are enabled and set in the PMA/FEC Direct PHY FPGA IP GUI? - Why don’t I see some HSSI analog parameters value set in the GTS PMA registers when these values are enabled and set in the PMA/FEC Direct PHY FPGA IP GUI?
Description Due to a problem in the Quartus® Prime Pro Edition Software version 24.3, when you set the below analog parameters in the GTS PMA/FEC Direct PHY IP GUI, the settings do not reflect in the GTS PMA registers when you perform a readback of these values following the register offset information provided by GTS PMA/FEC Direct PHY IP Register Map. Affected HSSI Analog Parameters set in ‘ Analog Parameters ’ Tab: ) Enable RX P&N Invert , Enable TX P&N Invert ) RX External Coupling Mode ) Selects the value of RX On-chip Termination Resolution To overcome this problem, you can use the QSF setting methodology to set the Analog parameters in your .qsf file for both the RX on-chip termination and RX External Coupling Mode settings. For TX and RX polarity inversion pins, you can follow the PMA/FEC Direct PHY IP User Guide on the GTS Attribute access method to change the TX and RX polarity pins. This problem is scheduled to be fixed in a future release of the Quartus® Prime Pro Edition Software.
