16.7.3. On-Die Termination Calibration

The Calibrate Termination feature lets you determine the optimal On-Die Termination and Output Drive Strength settings for your memory interface, for Arria 10 and later families.

The Calibrate Termination function runs calibration with all available termination settings and selects the optimal settings based on the calibration margins.

The Calibrate Termination feature is available for DDR3, DDR4, and RLDRAM 3 protocols, on Arria 10 devices.
