software selects in various configurations.
To ensure that you understand the 0 PPM clock driver rule, the Quartus II software
expects the following user assignment whenever you use the rx_coreclk port to drive
the receiver phase compensation FIFO read clock:
■
Failing to make this assignment correctly when using the rx_coreclk port results in a
Quartus II compilation error.
The GXB 0 PPM core clock setting user assignment allows the following clock
drivers to drive the rx_coreclk ports:

■
The Quartus II software does not allow gated clocks or clocks generated in FPGA
logic to drive the tx_coreclk ports.
Because the 0 PPM clock group assignment allows the 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.
