Enabling the EyeQ Control Logic and the EyeQ Hardware
You must enable the EyeQ hardware in the ALTGX MegaWizard Plug-In Manager
and the EyeQ control block in the ALTGX_RECONIG MegaWizard Plug-In Manager.

EyeQ uses an Avalon Memory Mapped interface. For more information about this
interface, refer to the
Connections Between the ALTGX and ALTGX_RECONFIG Instances
To enable the EyeQ options, follow these steps:
1. Enable the EyeQ options in the ALTGX and ALTGX_RECONFIG MegaWizard
2. Connect the reconfig_{to/from}gxb ports between the ALTGX and
EyeQ control logic in the dynamic reconfiguration controller allows you to write to
the registers in the EyeQ hardware. Therefore, you must have a state machine in the
user design that communicates to the EyeQ control block of the ALTGX_RECONFIG
instance. You can then access the internal registers of the EyeQ hardware indirectly
through the EyeQ control logic.
Altera recommends having an input pattern generator and checker to monitor the
BER of the received data.
EyeQ hardware is available for each transceiver channel in the receiver data path.
Select the Analog Controls option in the Reconfiguration Settings screen of the
ALTGX MegaWizard Plug-In Manager to enable the EyeQ hardware.
EyeQ control logic is available in the dynamic reconfiguration controller. Select the
EyeQ control option in the ALTGX_RECONFIG MegaWizard Plug-In Manager to
enable the EyeQ control logic.
