The PCI clamping diode must be disabled to drive an input with voltages higher than V
These input values overdrive the input buffer, so the pin leakage current is slightly higher than the default value.
To drive inputs higher than V
overdrive for LVTTL/LVCMOS input pins option in Device setting option in the Quartus II software.
