Altera Triple Speed Ethernet MegaCore Function - Manual (Page 35)

Parameter Value Name
This option is not supported in Stratix V,
Arria V, Arria V GZ, and Cyclone V devices.
Turn on this option to export the powerdown
signal of the GX transceiver to the top-level of
your design. Powerdown is shared among the
transceivers in a quad. Therefore, turning on this
option in multiport Ethernet configurations
maximizes efficient use of transceivers within
the quad.
Turn off this option to connect the powerdown
signal internally to the PCS control register
interface. This connection allows the host
processor to control the transceiver powerdown
in your system.
On/Off Export transceiver

This option is always turned on in devices other
than Arria GX and Stratix II GX. When this
option is turned on, the MegaCore function
includes the dynamic reconfiguration signals.
For designs targeting devices other than Arria V,
Cyclone V, Stratix V, and Arria 10, Altera
recommends that you instantiate the ALTGX_
RECONFIG megafunction and connect the
megafunction to the dynamic reconfiguration
signals to enable offset cancellation.
For Arria V, Cyclone V, and Stratix V designs,
Altera recommends that you instantiate the
Transceiver Reconfiguration Controller
megafunction and connect the megafunction to
the dynamic reconfiguration signals to enable
offset cancellation. The transceivers in the
Arria V, Cyclone V, and Stratix V designs are
configured with Altera Custom PHY IP core.
The Custom PHY IP core require two reconfig-
uration interfaces for external reconfiguration
controller. For more information on the
reconfiguration interfaces required, refer to the
Altera Transceiver PHY IP Core User Guide
and the respective device handbook.
For more information about quad sharing
considerations, refer to
Sharing PLLs in Devices
with GIGE PHY on page 8-6 .
