For example, in an Arria V or Stratix V device, to change the VOD setting for lane 9, you write logical
channel 10 to the Reconfiguration Controller.

Adding the Reconfiguration Controller
100G Interlaken IP core variations that target an Arria V or a Stratix V device require an external reconfi‐
guration controller to function correctly in hardware. 100G Interlaken IP core variations that target an
Arria 10 device include a reconfiguration controller block and do not require an external reconfiguration
controller.
Keeping the Reconfiguration Controller external to the IP core in Arria V and Stratix V devices provides
the flexibility to share the Reconfiguration Controller among multiple IP cores and to accommodate
FPGA transceiver layouts based on the usage model of your application. In Arria 10 devices, you can
configure individual transceiver channels flexibly through an Avalon-MM Arria 10 transceiver reconfigu‐
ration interface.
