This chapter describes the dynamic reconfiguration features available in Stratix
transceivers.
For information about features that will be supported in a future release of the
Quartus
Stratix V transceivers have a dedicated reconfiguration space to support the following
features:
■
■
You can use the transceiver reconfiguration controller to reconfigure the following
transceiver PMA controls:
■

■

For more information about the controller, its settings, and implementing it in your
design, refer to the Transceiver Reconfiguration Controller chapter of the
Transceiver PHY IP Core User
Every transceiver channel in Stratix V devices has offset cancellation circuitry to
compensate for the offset variations due to process. After the device powers up for the
first time, you can dynamically reconfigure the PMA controls only after the offset
cancellation and reset sequence are done, as indicated by the assertion of the
reconfig_busy output signal of the transceiver reconfiguration controller.
You can continue with subsequent reconfigurations of PMA controls when the
reconfig_busy status output is low.
For more information about the reset and powerdown of Stratix V transceivers, refer
to the
For more information about reconfiguring a specific PMA control, refer to “How to
Reconfigure a PMA Control” in the Transceiver Reconfiguration Controller chapter of the
