Hi hb0001,

 

I'm apologize for my mistake (I will delete the previous reply to avoid confusion).

 

Therefore, the recommended operation conditions VCCIO3V:

  • Minimum: 2.85 V
  • Typical: 3.00 V
  • Maximum: 3.15 V

 

In Intel Stratix 10 GX Dev kit, we are using step-down DC-DC switching converter (EN5319QI) in order to switch 3.3 to 3V.

You may refer to below schematic:
