The dynamic reconfiguration controller is a soft intellectual property (IP) that utilizes
FPGA-fabric resources. You can use only one controller per transceiver block. You
cannot use the dynamic reconfiguration controller to control multiple Cyclone IV
devices or any off-chip interfaces.

ALTGX_RECONFIG instance, refer to
Reconfiguration” on page
You can use one ALTGX_RECONFIG instance to control multiple transceiver blocks.
However, you cannot use multiple ALTGX_RECONFIG instances to control one
transceiver block.
ALTGX_RECONFIG MegaWizard Plug-In Manager
Represents analog controls (Voltage Output Differential [V
Manual Equalization) as displayed in both the ALTGX and ALTGX_RECONFIG MegaWizard
Plug-In Managers.
Refers to a transmitter channel, a receiver channel, or a duplex channel that has both PMA and
PCS blocks.
