Quartus II software selects in various configurations.
To ensure that you understand the 0 PPM clock driver rule, the Quartus II software
expects the following set of user assignments whenever you use the tx_coreclk port
to drive the transmitter phase compensation FIFO write clock:
■
Failing to make this assignment correctly when using the tx_coreclk port results in a
Quartus II compilation error.
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 FPGA
logic to drive the tx_coreclk ports.
Because the GXB 0 PPM core clock setting 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.
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.
