4.2.3. Assigning I/O Banks
Some Intel® FPGA devices support assignments to I/O banks. I/O banks are a logical grouping of I/O pins for convenience in making certain types of assignments, such as I/O standard assignments.
When you save your Pin Planner constraints, the pin location saves to the project .qsf that also saves the I/O bank locations as a comment. Command-line users can use this comment to identify I/O bank locations for the placed pins without launching the Intel® Quartus® Prime software GUI.
