3.3. Intel® Stratix® 10 EMIF Calibration
The calibration process enables the system to compensate for the effects of factors such as the following:
- Timing and electrical constraints, such as setup/hold time and Vref variations.
- Circuit board and package factors, such as skew, fly-by effects, and manufacturing variations.
- Environmental uncertainties, such as variations in voltage and temperature.
- The demanding effects of small margins associated with high-speed operation.
For a given external memory interface, calibration occurs in parallel for all DQS groups and I/O banks. For an I/O column containing multiple external memory interfaces, there is no particular calibration order in relation to the interfaces; however, for a given SRAM Object File (.sof), calibration always occurs in the same order.
