About pin processing of unused input pins for Cyclone V.

FPGA:Cyclone V (5CEBA7F23C7N)

 

Can I use the input setting IO pin in the open state when it is not used?

There is a model where the FPGA circuit is common and the external circuit is different, so the settings are common.

Hi YTsuj6,

 

The Unused Pins must connect as defined in the Quartus Prime software.

Below are the options for unused pins:

You can also set this on an individual pin-by-pin basis using the Pin Planner. Right-click a pin in the Package View, go to Reserved Pins, and select an option.
