13.7. Debugging Stratix® 10 EMIF IP

You can debug hardware failures by connecting to the Legacy EMIF Debug Toolkit or the EMIF Unified Calibration Debug Toolkit, or by exporting an Avalon® -MM slave port, from which you can access information gathered during calibration. You can also connect to this port to mask ranks and to request recalibration.

About the Legacy EMIF Debug Toolkit and the EMIF Unified Calibration Debug Toolkit

Commencing with the Stratix® 10 EMIF IP version 19.2.1 ( Quartus® Prime software version 20.2), two debug toolkits are available. In general, the two toolkits offer many similar features, however the Unified Toolkit does not require an installation of the Quartus® Prime software. In addition, it can read ISSPs and easily rerun the traffic generator.

The following table summarizes the features of the two debug toolkits:

Accessing the Exported Avalon® -MM Port

You can access the exported Avalon® -MM port in two ways:

  • Via the External Memory Interface Debug Toolkit
  • Via On-Chip Debug (core logic on the FPGA)
