Table 6–6 describes the settings available on the Advanced Options tab.
Table 6–6. Advanced Options
Name Value Description
Include control and status portsOn/Off
If you turn this option on, the top-level IP core include the status
signals and digital resets shown in XAUI Top-Level Signals—Soft
PCS and PMA and XAUI Top-Level Signals–Hard IP PCS and PMA. If
you turn this option off, you can access control and status
information using Avalon-MM interface to the control and status
registers. The default setting is off.
External PMA control and
configuration
On/Off
If you turn this option on, the PMA signals are brought up to the top
level of the XAUI IP Core. This option is useful if your design
includes multiple instantiations of the XAUI PHY IP Core. To save
FPGA resources, you can instantiate the Low Latency PHY Controller
and Transceiver Reconfiguration Controller IP Cores separately in
your design to avoid having these IP cores instantiated in each
instance of the XAUI PHY IP Core. If you turn this option off, the
PMA signals remain internal to the core. The default setting is off.
This option is available for Arria II GX, HardCopy IV and Stratix IV
devices. In these devices, this option must be turned On to fit 2 hard
XAUI instances in adjacent transceiver quads that share the same
calibration block. In addition, the instances must share powerdown
signals.
Enable rx_recovered_clk pin On/Off
When you turn this option on, the RX recovered clock signal is an
output signal.
