​Hi,

VCCIO PIN is connected to 5V right?

if so FPGA will be damaged.

if it's unused IO pin it should be connected to vccio or gnd. If you have pulled IO pin to 5volt we are operating device in maximum rating it will also damage the device.

we cannot guarantee reliability /performance if you are operating device in absolute maximum rating.
