Why does the IP upgrade fail for Intel® Arria® 10 FPGA Native PHY Intel® FPGA IP with manual CTLE mode and DFE enabled?

Description

Due to a problem with the Intel® Arria® 10 FPGA Native PHY Intel FPGA IP, the IP upgrade to the Intel® Quartus® Prime Software version 16.0 from previous software versions might fail if you set CTLE mode to "manual" and enable DFE for data rates < 4.5 Gbps. The valid DFE mode is "disabled" when CTLE mode = "manual". You might also observe IP upgrade failure if the Native PHY Intel FPGA IP has multiple reconfiguration profiles enabled and if any profile has a configuration with CTLE mode = "manual" and DFE enabled for data rates < 4.5 Gbps

Resolution

To fix this problem, follow these steps:

1. Open the Native PHY Intel FPGA IP in the IP parameter editor.
2. Load the configuration profile with CTLE mode = "manual" and DFE enabled for data rates < 4.5 Gbps.
3. Set DFE mode to "disabled".
4. Save and generate your IP.
