Max10 PCB Layout - Unused Pins

Hello, I am building my first from-scratch FPGA project. I’m using a Max10 10M02SC 153-MBGA, but my design is really simple. I really only need to use one bank because I only need about 16 I...

Any unused pin should be connected to PCB as a pad which doesn't route any where. This helps during assembly.

About the MAX10's clock, you might want to consider placing spare clock source as backup. MAX10's internal clock has big range of uncertainty. If your design doesn't care "exact time", then you will be okay. Another recommendation is to bring out test points on unused pins for debugging or for spare. It's just a practice. Lastly, review PCG-01018 document which is max10 fpga device family pin connection guidelines.
