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:

1. )    Enable RX P&N Invert, Enable TX P&N Invert
2. )    RX External Coupling Mode 
3. )    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.
