Hi
1) Is there option to define which VREF the FPGA use ? (interal FPGA vref or external IO pin )
If yes - where should I define it in the Quartus
2)Do all the banks should get same ...

Regular ContributorHello Yishay,
Hope you are doing well. You can define Vref by using Pin Planner in your Quartus. There is an external VREF pin for every I/O bank, providing one external VREF source for all I/Os in the same bank. You can refer to page 40 from Stratix 10 GPIO User Guide
Additional documents that you can refer to is as below:
1. Intel Stratix 10 Device Datasheet
Thank you.
