Importing the Quartus II estimation file automatically populates
the V
CCIO
voltages. However, certain designs may have
discrepancies. This occurs most often if I/O standards that are
listed as different voltages in the PowerPlay Early Power
Estimator spreadsheet can actually be in the same I/O bank on
the device.

For more information on I/O standard guidelines, see the Selectable I/O
Standards in the Arria GX Devices Handbook.
If there are discrepancies between the V
CCIO
voltages in banks, the
PowerPlay Early Power Estimator spreadsheet displays the following
message:
Bank and I/O voltage selection inconsistent with I/O Bank Voltage. See
the Bank Voltage column.
Ensure that the correct V
CCIO
is selected for the bank.
Figure 3–13 shows the PowerPlay Early Power Estimator spreadsheet
and the estimated power consumed by the I/O pins.
