2.6.2. Transceiver Logical Channel Numbering
In Arria V and Stratix V devices, logical channel numbering starts from zero. The logical channel numbering starts at the bottom of the die with logical channel 0 and continues in physical pin order through the four ordered transceiver blocks on the same side of the device. Each data channel and TX PLL has its own dedicated reconfiguration interface with an assigned logical channel.
In Intel® Arria® 10 devices, you control the mapping of Interlaken lanes directly in the Intel® Arria® 10 Native PHY IP core that is included in the 100G Interlaken IP core.
In Arria V and Stratix V devices, you can control the logical channel assignments in the IP core. You typically assign lanes to match the logical channel numbering. However, you can map the twelve Interlaken lanes in a 12-lane variation to any two adjacent transceiver blocks on the same side of the device. You can use the information in the following table to map the lanes to their default logical channel numbering. The logical channel numbering always starts at the bottom of a transceiver block.

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.
