3.15.2. On-Chip Debug for Arria® 10

The On-Chip Debug feature allows user logic to access the same debug capabilities as the External Memory Interface Toolkit. You can use On-Chip Debug to monitor the calibration results of an external memory interface, without a connected computer.

To use On-Chip Debug, you need a C header file which is provided as part of the external memory interface IP. The C header file defines data structures that contain calibration data, and definitions of the commands that can be sent to the memory interface.

The On-Chip Debug feature accesses the data structures through the Avalon-MM port that is exposed by the EMIF IP when you turn on debugging features.
