Arria10 GX I/O Pin Leakage Current

Hi, I found Input Leakage spec in Arria10 datasheet Table7. It shows that Max Ii = 80μA and Min Ii = -80μA. I understand the spec as following. If a input pin is pulled-up to 1.8V throug...

The leakage current number in the datasheet is just a specification (pass/fail) criteria...it doesnt mean that the IO pin itself is leaking that much of current. In fact, IO characteristic differ from pin to pin, device to device. For more accurate, it is advisable to run IO simulation e.g. IBIS.

    I No more need to make changes pull-up and pull-down by your answer.

    Thank you so much.

    Ok but how can we design? We as engineers usually use worst case values when we design. We can not change BOM from products to procuts. And to be honest, these leakage values shown in the datasheet are so high for a leakage parameter. Are you sure no mistakes in the values?
