There are three methods that you can use to dynamically reconfigure the PMA
controls of a transceiver channel:
■
■
■
Method 1: Using logical_channel_address to Reconfigure Specific Transceiver
Channels
Enable the logical_channel_address port by selecting the Use
‘logical_channel_address’ port option on the Analog controls tab. This method is
applicable only for a design where the dynamic reconfiguration controller controls
more than one channel.
You can additionally reconfigure either the receiver portion, transmitter portion, or
both the receiver and transmitter portions of the transceiver channel by setting the
corresponding value on the rx_tx_duplex_sel input port. For more information, refer
to
Connecting the PMA Control Ports
The selected PMA control ports remain fixed in width, regardless of the number of
channels controlled by the ALTGX_RECONFIG instance:
■
■
■
■
Write Transaction
To complete a write transaction, perform the following steps:
1. Set the selected PMA control ports to the desired settings (for example,
2. Set the logical_channel_address input port to the logical channel address of the
3. Set the rx_tx_duplex_sel port to 2'b10 so that only the transmit PMA controls are
4. Ensure that the busy signal is low before you start a write transaction.
5. Assert the write_all signal for one reconfig_clk clock cycle.
The busy output status signal is asserted high to indicate that the dynamic
reconfiguration controller is busy writing the PMA control values. When the write
transaction has completed, the busy signal goes low.
