Altera PowerPlay Early Power Estimator - Manual (Page 49)

Module Parameters Description
SDRAM
Frequency Enter the operating frequency of the selected DDR protocol
used.
Type Select the DDR protocol used.
Data Width Select the width of the data lines (in bits).
Peripherals
Usage Select On for module in use. Turn on the appropriate voltage for
one of the I/O banks before selecting the module.
Voltage Select the voltage used for this module.
Report Worksheet
The Report worksheet shows all the information and power estimation results from the PowerPlay EPE
spreadsheet. You can find the power supply recommendations in the Power Supply Current (A) section,
which describes all the power supply requirements for the device that your design uses in the Min Current
Requirement (A) and the User Mode Current Requirement (A) columns.
The Min Current Requirement (A) column is not available for MAX 10 devices.
Static Power and Dynamic Current per Voltage Rail
The Report worksheet shows all the information and power estimation results from the PowerPlay EPE
spreadsheet. You can find the power supply recommendations in the Power Supply Current (A) section,
which describes all the power supply requirements for the device that your design uses in the Min Current
Requirement (A) and the User Mode Current Requirement (A) columns.

Power Up Current
In some device families, the power up current can be larger than the dynamic current required in the I/O
worksheet. For example, in Stratix III and Stratix IV devices, the I
CCPD
value on the I/O worksheet is
different than the Minimum current requirement for I
CCPD
in Report worksheet.
Altera provides the minimum current required for the V
CCPD
power rail for each voltage supply used, but
is not dependent on how many banks use that voltage supply.
To estimate the power up current, use the Report worksheet and compare the minimum current require‐
ment with user mode current requirement.
