Example 9-1: Informational Messages for the Transceiver Reconfiguration Interface

PHY IP will require 2 reconfiguration interfaces for
connection to the external reconfiguration controller.
Reconfiguration interface offset 0 is connected to the transceiver channel.
Reconfiguration interface offset 1 is connected to the transmit PLL.

Table 9-26: Reconfiguration Interface

This interface uses the Avalon-MM PHY Management interface clock.

Description

reconfig_to_xcvr [( <n> 70-1):

0]

Input

Reconfiguration signals from the

Transceiver Reconfiguration

Controller. <n> grows linearly with

the number of reconfiguration

interfaces.

reconfig_from_xcvr [( <n> 46-1)

:0]

Output

Reconfiguration signals to the

Transceiver Reconfiguration

Controller. <n> grows linearly with

the number of reconfiguration

interfaces.

Transceiver dynamic reconfiguration requires that you assign the starting channel number if you are

using ×6 or ×N bonding. Logical channel 0 should be assigned to either physical transceiver channel 1 or

channel 4 of a transceiver bank. However, if you have already created a PCB with a different lane

assignment for logical lane 0, you can use the workaound shown in the following example to remove this

restriction. The example redefines the

pma_bonding_master

parameter using the Quartus II Assignment

Editor. In this example, the

pma_bonding_master

was originally assigned to physical channel 1. (The

original assignment could also have been to physical channel 4.) The to parameter reassigns the

pma_bonding_master

to the Custom PHY instance name. You must substitute the instance name from

your design for the instance name shown in quotation marks
