Input Parameter
Description
Package
Select the package that is used.
Larger packages provide a larger cooling surface and more contact
points to the circuit board, leading to lower thermal resistance.
Package selection does not affect dynamic power.
Temperature Grade
Select the appropriate temperature grade. This field affects the
allowed maximum junction temperature range. This field can also
be used to determine core voltage for some device families.
Different device families support different temperature grades. For
more information about the supported temperature grade and the
recommended operating range for the device junction tempera‐
ture, refer to the respective device family datasheet.
Power Characteristic
Select typical or theoretical worst-case silicon process.
There is a process variation from die-to-die. This primarily
impacts the static power consumption. Typical power character‐
istic provides results that line up with average device measure‐
ments.
Maximum power characteristic provides results that line up with
worst-case device measurements. To ensure your power supply
design is sufficient to handle the worst-case process variation that
affects static power consumption, Altera recommends using the
Maximum power characteristic for your power estimation. To
enable the Enpirion device selection, you must set Power
Characteristics to Maximum.
V
CCINT
Voltage (V)
For Cyclone IV E devices, select the following V
CCINT
voltage:
• For devices with speed grade C8L, C9L and I8L, set the V
CCINT
to 1.0V.
• For devices with speed grade C6, C7, C8, I7 and A7, set the
VCCINT to 1.2V.
V
CC_ONE
Voltage (V)
For MAX 10 devices only, select 3.0 V or 3.3 V. The voltage is
internally regulated to 1.2 V to supply power to the core and
periphery.
Power Model Status
This shows if the power model for the device is in preliminary or
final version and is only available from EPE 14.0 onwards.
V
CCL
Voltage (V)
For Stratix III devices, select the following V
CCL
voltage:
• For devices with speed grade –4L, this value can either be 0.9 V
or 1.1 V.
• For devices with other speed grades, set the VCCL voltage level
to 1.1 V.
