3.5.1. I/O Aux Sharing

The I/O Aux contains a hardened processor and dedicated memory storing the calibration software code and data.

When a column contains multiple memory interfaces, the hardened processor calibrates each interface serially. Interfaces placed within the same I/O column always share the same I/O Aux. The Quartus® Prime Fitter handles I/O Aux sharing automatically.
