I tried to set the F-tile:
- FHT
- Number of PMA lanes: 4
- System PLL
- PAM4
- PMA width: 128
- Disable RS-FEC
I use the example "FHT PAM4 4 400G 4 PMA lanes RSFEC 544/514" in F-tile PMA/FEC Direct PHY Intel FPGA IP. But, I want to disable the RS-FEC. I only click the "Enable RS-FEC", this shuts down the RS-FEC. And I open the example_design -> rtl -> param_desines1.iv, comment the "`define RSFEC_TESTWRAP 1". Then, Quartus 22.4 starts compiling.
At the Logic generation, I get errors.
Error (21842): Support logic cannot be generated because IP components used in the design have conflicting settings

Please help me check the source of the problem, is it a bug?

Hi,
If you select any of the four available Example Design Options, but change the F-Tile PMA/FEC Direct PHY Intel® FPGA IP settings in the GUI thereafter, the example design generated does not follow the changed settings for the F-Tile PMA/FEC Direct PHY Intel® FPGA IP. The example design generation only takes the Example Design Options listed in Example Design Generation Options. Any other changes that you make to the F-Tile PMA/FEC Direct PHY Intel® FPGA IP settings are not applied during example design generation.
Clicking Generate Example Design completes the IP Generation and Support-logic Generation stages of the Compiler.
For more info please refer to the below link.
Hope this will resolve your issue.
Thank you
