New ContributorIntel 10M25SAE144I7G FPGA failure
Hi, Greetings! History: We are using Intel 10M25SAE144I7G FPGA in the design. Rev1 Board is working fine Rev 2 Board we used the same FPGA design code and some of the pins assigned as input/ out...

ContributorYou should never leave inputs just floating, as a basic general rule of hardware design. Floating inputs can drift into the transition region and/or oscillate, which can cause noise, excess power consumption, and excess heat. It is possible that this phenomenon led to destruction of components in your circuit.

Super ContributorAlthough floating inputs should be avoided, they'll hardly cause FPGA damage. Overvoltage beyond maximum rating is more likely to cause FPGA damage.
To bypass possible floating input problems, you can assign weak pull-up in assignment editor or pin planner to possibly unconnected inputs.
