The PMA control ports for the ALTGX_RECONFIG MegaWizard Plug-In Manager are
available in the Analog controls screen. You can select the PMA control ports you
want to reconfigure. For example, to use tx_vodctrl to write new V
use tx_vodctrl_out to read the existing V
Dynamically Reconfiguring PMA Controls
You can dynamically reconfigure the PMA controls of a transceiver channel using
three methods:
■
■
■
For the above three methods, you can additionally use the rx_tx_duplex_sel[1:0]
port transmitter and receiver parameters. For more information, refer to
Reconfiguration Controller Port List” on page
Method 1—Using the logical_channel_address Port
Using Method 1, you can dynamically reconfigure the PMA controls of a transceiver
channel by using the logical_channel_address port without affecting the remaining
active channels. Enable the logical_channel_address port by selecting the Use
'logical_channel_address' port for Analog controls reconfiguration option in the
Analog controls screen of the ALTGX_RECONFIG MegaWizard Plug-In Manager.
This method is applicable only for a design where the dynamic reconfiguration
controller controls more than one channel.
When using Method 1, the selected PMA control write and read ports remain fixed in
width, regardless of the number of channels controlled by the ALTGX_RECONFIG
instance.
To observe the width of the PMA control ports, refer to the ALTGX_RECONFIG
MegaWizard Plug-In Manager.
The value you set at the PMA control ports is only written into the specified
transceiver channel.
Ensure that the busy signal is low before you start a write or read transaction. The
busy output status signal is asserted high when the dynamic reconfiguration
controller is occupied writing or reading the PMA control values. When the write or
read transaction has completed, the busy signal goes low.
Reconfiguring the PMA controls of a specific transceiver channel. For more
information, refer to
Dynamically reconfiguring the PMA controls of the transceiver channels without
using the logical_channel_address port (where all transceiver channels are
reconfigured). If you use this method, the PMA controls of all the transceiver
channels connected to the dynamic reconfiguration controller are reconfigured.
For more information, refer to
Channels” on page
Dynamically reconfiguring the PMA controls of the transceiver channels without
using the logical_channel_address port (where only the PMA controls of the
transceiver channels are reconfigured). If you use this method, each channel has its
own PMA control port. Based on the value set at the ports, the PMA controls of the
corresponding transceiver channels are reconfigured. For more information, refer
