S-10 Transceiver IO Terminations

Hi,

I am using stratix 10 SoC dev kit with Transceivers with 10Gbps speed. 

There, I want to use External termination for the transceiver receiver pins. As per the L tile user guide, we can set r_unused option in the native PHY.[Table 23. RX Analog PMA Settings Options]

I checked setting the same in Native PHY, the error message is listed saying that r_unused as invalid. What is the procedure to set external termination for receiver pins?

Also, I checked with "set_instance_assignment " commands & seeing no impact on these commands.

set_instance_assignment -name HSSI_PARAMETER "pma_rx_buf_term_sel= r_unused" -to AH45

set_instance_assignment -name HSSI_PARAMETER pma_rx_buf_term_sel= r_unused -to AL43

Hi,

Quick update.

 Quartus tool is ignoring the "set_instance_assignment " constraints in the QSF file.

"Warning(332145): Command "set_instance_assignment" found in SDC file is not a proper SDC command and is being ignored "

 

With regards,
