6.4. Multiple Reconfiguration Profiles
When you enable multiple reconfiguration profiles feature, the Native PHY and ATX PLL IP cores can generate configuration files for all the profiles in the format desired (SystemVerilog package, MIF, or C header file). The configuration files are located in the <IP instance name>/reconfig/ subfolder of the IP instance with the configuration profile index added to the filename. For example, the configuration file for Profile 0 is stored as <filename_CFG0.sv>. The Quartus Prime Timing Analyzer includes the necessary timing paths for all the configurations based on initial and target profiles. You can also generate reduced configuration files that contain only the attributes that differ between the multiple configured profiles. You can create up to eight reconfiguration profiles (Profile 0 to Profile 7) at a time for each instance of the Native PHY/ATX PLL IP core.
You can optionally allow the Native PHY IP core to include PMA Analog settings in the configuration files by enabling the feature Include PMA Analog settings in configuration files in the Dynamic Reconfiguration tab of the Transceiver Native PHY IP Parameter Editor. This feature is disabled by default. Enabling this feature adds the PMA analog settings specified in the Analog PMA settings (Optional) tab of the 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. Refer to the Analog Parameter Settings chapter for details about QSF assignments for the analog settings.
Refer to Steps to Perform Dynamic Reconfiguration for a complete list of steps to perform dynamic reconfiguration using the IP guided reconfiguration flow with multiple reconfiguration profiles enabled.
The Quartus Prime Timing Analyzer Timing Analyzer only includes the necessary PCS timing paths for all the profiles. To perform a PMA reconfiguration such as TX PLL switching, CGB divider switching, or reference clock switching, you must use the flow described in Steps to Perform Dynamic Reconfiguration. Refer to Timing Closure Recommendations for more details about enabling multiple profiles and running timing analyses.
You can use the multiple reconfiguration profiles feature without using the embedded reconfiguration streamer feature. When using the multiple reconfiguration profiles feature by itself, you must write the user logic to reconfigure all the entries that are different between the profiles while moving from one profile to another.
