I/O Standard in Pin planner of Intel Quartus prime

Hello all, Is it possible to change I/O standard in Pin planner other than the given options. For ex. 3.3 V LVTTL is there in given options but I need to change it as 3.5V but in given I/O standard ...

Hi,
you can refer to device datasheet to learn about supported IO standards. No recent FPGA family supports higher nominal IO supply voltage than 3.3V (+/- 5 % tolerance).

It will be typically no problem to connect peripherals using non-standard 3.5V logic supply, you should worry however about possible overshoot that might exceed absolute maximum input voltage of 4.2V.

Thank You. But how can we give pin input setting to 3.5V LVTTL or 3.8V LVTTL and generate a power report. Is it possible? Because we need to check how it will affect instead of 3.3v LVTTL to 3.5 OR 3.8V LVTTL and need to check the power report and need to check behavior in simulation
