Quartus II software selects in various configurations.
To ensure that you understand the 0 PPM clock driver rule, the Quartus II software
expects the “GXB 0 PPM Core Clock Setting” user assignment whenever you use the
tx_coreclk port to drive the transmitter phase compensation FIFO write clock.
Failure to make this assignment when using the tx_coreclk port results in a
Quartus II compilation error.
GXB 0 PPM Core Clock Setting
The GXB 0 PPM core clock setting is intended for advanced users who know the
clocking configuration of the entire system and want to reduce the FPGA fabric global
and regional clock resource utilization. The GXB 0 PPM core clock setting allows the
following clock drivers to drive the tx_coreclk ports:

The Quartus II software does not allow gated clocks or clocks generated in the FPGA
logic to drive the tx_coreclk ports.
Because the GXB 0 PPM core clock setting allows FPGA CLK input pins and
transceiver REFCLK pins as the clock driver, 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 tx_coreclk ports has a 0 PPM
difference with respect to the FIFO read clock in those channels.
