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 [( 70-1):

0]

Input

Reconfiguration signals from the

Transceiver Reconfiguration

Controller. grows linearly with

the number of reconfiguration

interfaces.

reconfig_from_xcvr [( 46-1)

:0]

Output

Reconfiguration signals to the

Transceiver Reconfiguration

Controller. 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
