When you use this mode, the ALTGX MegaWizard Plug-In Manager allows you to
select one or more channels from the What is the number of channels? option on the
General screen.
If you select the number of channels to be less than four, the remaining transmitter
channels cannot be used within the transceiver block. Therefore, if you have more
than one instance configured in Transmit Only or Receiver and Transmitter mode
with the ×4 option enabled, the Quartus II software cannot combine the instances
within the same transceiver block.
Only the transmitter channels share a common clock. The receiver channels are
clocked independently. Therefore, you can configure the unused receiver channels
within a transceiver block in any allowed configuration. For example, assume that
you configure the ALTGX MegaWizard Plug-In Manager with the options shown in
Table
Table 3–6. General Screen Options in Basic ×4 Mode for Arria II Devices
If you create the instance with the above selection, you cannot use the remaining two
transmitter channels in the transceiver block. However, you can use the remaining
two receiver channels in a different configuration.
