Description of Transceiver Channel Reconfiguration Modes
7. Core Fabric-Transceiver Channel Interface Selection
This section describes the ALTGX MegaWizard Plug-In Manager settings related
to the core fabric-Transceiver channel interface data width when you select and
activate Channel and CMU PLL Reconfiguration mode. You need to set up the
core fabric-Transceiver channel interface data width when channel reconfiguration
involves the following:
■ Functional mode reconfiguration involving changes in the core
fabric-Transceiver channel data width
■ Functional mode reconfiguration involving enabling and disabling the static
PCS blocks of the transceiver channel
You can set up the core fabric-Transceiver channel interface data width by
enabling the Channel Interface option in the Reconfig screen, as shown in
Figure 2–46.
Enable the Channel Interface option if the reconfiguration of the transceiver
channel involves the following changes:
■ The reconfigured channel has a changed core fabric-Transceiver channel
interface data width
■ The reconfigured channel has changed input control signals and output status
signals
