Stratix 10 I/O count discrepancy

Hello, I have a design with 371 I/O pins that I'm attempting to fit into a 1SG040HH3F35E3VG device. According to the Intel documentation and the Pin Planner, this device should have 374 user I/...

    Hello,

    These pins are unassigned so you can safely ignore it.

    Thank you

I was able to reduce the IO count of my design, constrain all pins to I/O banks and eventually get everything to fit.

The current design has 371 pins in use and 3 spares, for a total of 374 pins ... which is the expected pin count.

I don't understand why the tools were reporting only 366 pins available before, but it is working now.

Quartus Prime Pro is actually now reporting that I am using 389 pins, however this includes 18 "unassigned" pins that are showing up in the output pins report (see attached image).

These pins are not part of my design and I don't know where they came from. Can these pins be safely ignored?

Thanks,

Terry
