Because the 0 PPM clock group assignment allows the FPGA CLK input pins and
transceiver REFCLK pins as clock drivers, the Quartus II compiler cannot determine if
there is a 0 PPM difference between the FIFO write clock and read clock for each
channel.
You must ensure that the clock driver for all connected rx_coreclk ports has a 0 PPM
difference with respect to the FIFO write clock in those channels.
