• PMA analog settings that are device dependent
— These settings may vary for each transceiver protocol-type and data rate in
your design.
— These settings are not included in the configuration files by default. To include
these analog settings in the configuration files, you must enable the feature
Include PMA Analog settings in configuration files under the Dynamic
Reconfiguration tab of the Transceiver Native PHY IP Parameter Editor.
Enabling this feature will add the PMA analog settings specified in the Analog
PMA settings (Optional) tab of Native PHY IP Parameter Editor to the
configuration files. Even with this option enabled in the Native PHY IP
Parameter Editor, you must still specify QSF assignments for your analog
settings when compiling your static design. The analog settings selected in the
Native PHY IP Parameter Editor are used only to include these settings and
their dependent settings in the selected configuration files. For details about
optional analog settings, refer to the "Analog PMA Settings (Optional) for
Dynamic Reconfiguration" table in the Ports and Parameters section. For
details about QSF assignments for the analog settings, refer to the Analog
Parameter Settings chapter.
— If the Include PMA analog settings in configuration files option is
disabled, then you must set these PMA analog settings. In addition to
streaming the configuration files generated by the Native PHY IP Parameter
Editor, you must perform RMWs using Direct Reconfiguration Flow to change
these PMA analog settings through the Avalon-MM reconfiguration interface.
— The values of all these PMA analog settings that change when changing
protocol-type or data rates must be obtained from the respective Fitter reports
by performing full compilation for each of the base and target configurations.
— For example, when changing the data rate from A to B, you must first perform
a full compile with the data rate configured to A and note the PMA analog
settings from the fitter report. Next, you must perform a full compile with data
rate configured to B and note the PMA analog settings from the fitter report. If
any of these PMA analog settings changed values between the two compiles,
you must perform RMWs with the target values to the respective registers
after streaming the configuration files.
— Examples: Slew rate, Equalizer Bandwidth, Compensation Enable.
