There are two signals available when you enable the Channel Interface option:

In addition to these two ports, you can select the necessary control and status signals
for the reconfigured channel in the Clocking/Interface screen.
For more information about control and status signals, refer to the “Transceiver Port
Lists” section in the
These control and status signals are not applicable in Basic (PMA Direct) functional
mode.

Channel Interface Option Enabled
The Quartus II software has legal checks for the connectivity of tx_datainfull and
rx_dataoutfull and the various control and status signals you enable in the
Clocking/Interface screen.
For example, the Quartus II software allows you to select and connect the pipestatus
and powerdn signals. It assumes that you are planning to switch to and from PCIe
functional mode.
channel interface signals.
tx_datainfull—The width of this input signal depends on the number of
channels you set up in the General screen. It is 44 bits wide per channel. This
signal is available only for Transmitter only and Receiver and Transmitter
configurations. This port replaces the existing tx_datain port.
rx_dataoutfull—The width of this output signal depends on the number of
channels you set up in the General screen. It is 64 bits wide per channel. This
signal is available only for Receiver only and Receiver and Transmitter
configurations. This port replaces the existing rx_dataout port.
