Connections Between the ALTGX and ALTGX_RECONFIG Instances
Enable the adaptive equalization options in the ALTGX and ALTGX_RECONFIG
MegaWizard Plug-In Managers, as explained in the previous section. To use the AEQ
control block and AEQ hardware, you must connect the ALTGX receivers to the
ALTGX_RECONFIG instance using the reconfig_{to/from}gxb and
aeq_{to/from}gxb ports. You must also connect the ALTGX_RECONFIG instance to
your design.
If you have multiple transceiver instances and a single ALTGX_RECONFIG instance,
connect the LSB of the aeq_togxb[] and aeq_fromgxb[] ports of the
ALTGX_RECONFIG instance to the transceiver channel with a
logical_channel_address value of 0.
