max10 io standards

Hello everybody, I am reading the max10 specs, searching what IO standard options are available, and i am not sure what the "2,5V" means. For 3.3V there are separate LVTTL and LVCMOS options availab...

    Hi,
    for 1.8 V and 2.5 V VCCIO, separate LVTTL and CMOS I/O standards don't exist. Not sure why they are listed in device handbook, but you'll notice that they have identical electrical parameters in datasheet and support same current srength values.
    In MAX10 IBIS model, the 1.8 and 2.5V standards are designated LVCMOS. IBIS models also give the most detailed representation of I/O characteristics.
