XAUI PHY Dynamic Reconfiguration for Arria II GX, Cyclone IV GX,
HardCopy IV GX, and Stratix IV GX
The Arria II GX, Cyclone IV GX, HardCopy IV GX, and Stratix IV GX use the ALTGX_RECONFIG
Mega function for transceiver reconfiguration.
For more information about the ALTGX_RECONFIG Megafunction, refer to ALTGX_RECONFIG
Megafunction User Guide for Stratix IV Devices in volume 2 of the Stratix IV Device Handbook.
If your XAUI PHY IP Core includes a single transceiver quad, these signals are internal to the core. If your
design uses more than one quad, the reconfiguration signals are external.

Description
reconfig_to_xcvr[3:0]
Input
Reconfiguration signals from the Transceiver Reconfigu‐
ration IP Core to the XAUI transceiver.
reconfig_from_xcvr[<n>:0]
Output
Reconfiguration signals from the XAUI transceiver to the
Transceiver Reconfiguration IP Core. The size of this bus
is depends on the device. For the soft PCS in Stratix IV GX
and GT devices, <
n
> = 68 bits. For hard XAUI variants,
<
n
> = 16. For Stratix V devices, the number of bits
depends on the number of channels specified. Refer to
Chapter 16, Transceiver Reconfiguration Controller IP
Core for more information.

XAUI PHY Dynamic Reconfiguration for Arria V, Arria V GZ, Cyclone V and
Stratix V Devices
The Arria V, Arria V GZ, Cyclone V, and Stratix V devices use the Transceiver Reconfiguration
Controller IP Core for dynamic reconfiguration.
For more information about this IP core, refer to Chapter 16, Transceiver Reconfiguration Controller IP
Core.
Each channel and each TX PLL have separate dynamic reconfiguration interfaces. The MegaWizard Plug-
In Manager provides informational messages on the connectivity of these interfaces.
