3.4.6. DDR4 Calibration

The Intel® Arria® 10 GX FPGA Development Kit Reference Platform includes special mechanisms to ensure the functional stability of the Intel® Arria® 10 silicon. For example, the DDR4 memory might not calibrate successfully after FPGA reconfiguration.

The driver within the a10_ref Reference Platform can detect a failed calibration via the Uniphy Status to AVS IP, and retrigger calibration through the ddr4_calibrate IP block.
