Does altering the FPGA IO standard actually change something in hardware?

Hello to the community. Here is a background/precondition of the question in the heading. I entered the realm of FPGA development using Verilog, DE10-Lite (MAX10 series) and Quartus Prime Lite Editi...

    Hello, 

     

    VCCIO if powering the IO banks of the IO , depending of where the IO is located. 

    eg. If you power VCCIO -> 3.3V, the IO standard located in that IO bank should be 3.3V based IO. 
    The IO assignment in Quartus pin planner must be aligned with the physical setup on your board. 

     

    regards,

Yes, I've got that already. :-)

The only thing I needed was the unambiguous answer to the question in the heading of the topic. Something like "Yes, there are some setup in the hardware, but we won't tell which exactly. Use the software!". :-D
