Due to a problem in the Intel® Quartus® Prime Pro Edition software version 22.2 or 22.3, a compilation error may occur during Logic Generation with some valid assignments of TX equalization combinations on the F-Tile FGT channel.
Error example:
Error(21842): Support logic cannot be generated because IP components used in the design have conflicting settings

To work around this problem in the Intel® Quartus® Prime Pro Edition Software version 22.2 or 22.3, follow the steps below:
1. Check the TX equalization setting in F-Tile TX Equalizer Tool
2. Write equalization value to lane register offset 0x47830
This problem has been fixed in the Intel® Quartus® Prime Pro Edition Software version 23.1.
