Figure 3–9
You can dynamically reconfigure the transceiver channel from an existing functional
mode to a different functional mode by selecting the Channel Reconfiguration option
in ALTGX and ALTGX_RECONFIG MegaWizards. The blocks that are reconfigured
by channel reconfiguration mode are the PCS and RX PMA blocks of a transceiver
channel.
For more information about reconfiguring the RX PMA blocks of the transceiver
channel using channel reconfiguration mode, you can refer to
Reconfiguration Mode Using RX Local Divider” on page
In channel reconfiguration, only a write transaction can occur; no read transactions
are allowed. You can optionally choose to trigger write_all once by selecting the
continuous write operation in the ALTGX_RECONFIG MegaWizard Plug-In
Manager. The Quartus II software then continuously writes all the words required for
reconfiguration.
For channel reconfiguration, .mif files are required to dynamically reconfigure the
transceivers channels in channel reconfiguration modes. The .mif carries the
reconfiguration information that will be used to reconfigure the transceivers channel
dynamically on-the-fly. The .mif contents is generated automatically when you select
the Generate GXB Reconfig MIF option in the Quartus II software setting. For
different .mif settings, you need to later reconfigure and recompile the ALTGX
MegaWizard to generate the .mif based on the required reconfiguration settings.
The dynamic reconfiguration controller can optionally perform a continuos write
operation or a regular write operation of the .mif contents in terms of word size
(16-bit data) to the transceivers channel that is selected for reconfiguration.
