13.7.2. Debugging with the External Memory Interface Unified Calibration Debug Toolkit

The External Memory Interface Unified Calibration Debug Toolkit for Intel® Stratix® 10 FPGAs provides access to data collected by the Nios® II sequencer during memory calibration, and provides analysis tools for evaluating the calibrated interface stability and assessing hardware conditions.

The toolkit provides the following reports:

  • Interface and memory configuration, such as external memory protocol and interface width.
  • Calibration results including status (pass/fail), failure stage (if applicable), delay settings and margins, VREF settings and margins.

The available tasks and analysis tools enable the following:

  • Requesting recalibration of the memory interface.
  • Reading the probe data or writing the source data to the In-System Sources and Probes (ISSPs) instances in the design.
  • Viewing the delay setting on any pin in the selected interface and updating it if necessary.
  • Rerunning the traffic generator in the example design.
  • Running VREF Margining on the interface.
  • Running Driver Margining on the interface.
  • Calibrating or update the termination settings.
