7.11. XAUI PHY Ports
Figure 38 illustrates the top-level signals of the XAUI PHY IP Core for the hard IP implementation. This variant is available for Arria II GX, Cyclone IV GX, HardCopy IV and Stratix IV GX devices.Figure 39 illustrates the top-level signals of the XAUI PHY IP Core for the soft IP implementation. With the exception of the optional signals available for debugging and the signals for dynamic reconfiguration of the transceivers, the top-level signals of the two variants is nearly identical. The DDR XAUI soft IP signals and behavior are the same as the soft IP implementation.
The block diagram shown in the MegaWizard Plug-In Manager GUI labels the external pins with the interface type and places the interface name inside the box. The interface type and name are used to define component interfaces in the _hw.tcl. If you turn on Show signals, the block diagram displays all top-level signal names.
For more information about _hw.tcl files refer to refer to the Component Interface Tcl Reference chapter in volume 1 of the Intel® Quartus® Prime Handbook.
The following figure illustrates the top-level signals of the XAUI PHY IP Core for the soft IP implementation for both the single and DDR rates.
