Description
However, there is additional resistance present between the device ball
and the input of the receiver buffer, as shown in
resistance is because of package trace resistance (which can be calculated
as the resistance from the package ball to the pad) and the parasitic layout
metal routing resistance (which is shown between the pad and the
intersection of the on-chip termination and input buffer).

MultiVolt I/O Interface
The Stratix architecture supports the MultiVolt I/O interface feature,
which allows Stratix devices in all packages to interface with systems of
different supply voltages.
The Stratix VCCINT pins must always be connected to a 1.5-V power
supply. With a 1.5-V V
3.3-V tolerant. The VCCIO pins can be connected to either a 1.5-V, 1.8-V,
2.5-V, or 3.3-V power supply, depending on the output requirements.
