Table 3–5 describes the I/O bank parameters in the I/O section of the
PowerPlay Early Power Estimator.
Figure 3–11 shows how the V
CCIO
level is listed for each I/O bank. The
PowerPlay Early Power Estimator spreadsheet shows the I
CCIO
listed for
each bank. Select the V

I
CCI O
(A) This shows the total supply current due to the I/O pins in each I/O bank. This may be
higher than the thermal power due to current supplied to off-chip termination resistors.
Unassigned This represents the I
CCI O
of all I/O modules not assigned to an I/O bank.

Column Heading Description
Module Enter a name for the module in this column. This is an optional value.
I/O Standard Select the I/O standard used for the input, output or bidirectional pins in this module
from the list. The calculated I/O power varies based on the I/O standard.
Drive Strength/ On-chip
Termination Select the drive strength or on-chip termination implemented for the I/O pin(s) in this
module. Drive strength and on-chip termination are mutually exclusive.
