The following are the channel reconfiguration mode options:
■
■
Channel Interface Reconfiguration Mode
Enable this option if the reconfiguration of the transceiver channel involves the
following changes:
■
■
■
The following are the new input signals available when you enable this option:
■
■
Channel interface reconfiguration
Data rate division at receiver channel
The reconfigured channel has a changed FPGA fabric-Transceiver channel
interface data width
The reconfigured channel has changed input control signals and output status
signals
The reconfigured channel has enabled and disabled the static PCS blocks of the
transceiver channel
tx_datainfull—the width of this input signal depends on the number of
channels you set up in the ALTGX MegaWizard Plug-In Manager. It is 22 bits wide
per channel. This signal is available only for Transmitter only and Receiver and
Transmitter configurations. This port replaces the existing tx_datain port.
rx_dataoutfull—the width of this output signal depends on the number of
channels you set up in the ALTGX MegaWizard Plug-In Manager. It is 32 bits wide
per channel. This signal is available only for Receiver only and Receiver and
Transmitter configurations. This port replaces the existing rx_dataout port.
The Quartus II software has legality checks for the connectivity of
tx_datainfull and rx_dataoutfull and the various control and status
signals you enable in the Clocking/Interface screen. For example, the Quartus II
software allows you to select and connect the pipestatus and powerdn signals.
It assumes that you are planning to switch to and from PCI Express (PIPE)
functional mode.
