What transceiver PMA settings should I use when disabling “Use default TX PMA analog settings” and “Use default RX PMA analog settings” in the Intel Stratix 10 L-Tile or H-Tile device Native PHY IP?

Description

You should perform transceiver signal integrity simulation to determine what TX and RX PMA settings to use for your Intel Stratix® 10 device transceiver links.

Workaround/Fix

The TX and RX Termination settings are chosen by Quartus based on data rate when the “Use default TX PMA analog settings” and “Use default RX PMA analog settings” are enabled. If you use different values, you can use the default settings as a starting point and perform signal integrity analysis to assess your channel performance.

You can compile your Quartus® design and inspect the fitter results to determine the default TX and RX Termination settings for your Native PHY variant.
