Power Estimation Using the PowerPlay Early Power Estimator
December 2010 Altera Corporation PowerPlay Early Power Estimator for Altera CPLDs User Guide
Power Supply Current
The power supply current, shown in mA, provides the estimated current
consumption for power supplies. The I
CCPOWERUP
is only applicable during power up
when the configuration flash memory (CFM) block downloads to the SRAM. The
I
CCINT
current is the supply current required from V
CCINT
. The total I
CCIO
current is the
supply current required from V
CCIO
for all I/O banks. For more information about the
estimates of I
CCIO
based on I/O banks, refer to the “I/O Worksheet” on page 2–9 .
Table 2–4 lists the power supply current parameters in the PowerPlay EPE
spreadsheet, as shown in Figure 2–1 on page 2–1 .
Other Input Section
Figure 2–3 shows the four buttons under the other input parameters section in the
PowerPlay EPE spreadsheet.
Table 2–5 lists the four buttons under the other input parameters section in the
PowerPlay EPE spreadsheet.
