Hi,
the vddio has the big current. So the electromigration and IR drop is needed to considerated. So how to decide to the vddio power line width? So it depends on the average current or peak current?
Thanks!
Thanks!
But if the IR drop is caculated based on the peak current. It will be very large IR drop. And if the IR drop is caculated based on the average current,the IR drop is accepetable.
So how to decide the power width?
