Power Estimator

Input Values

The sections in the PowerPlay early power estimator that estimate I

and

power represent an architectural feature of the device, such as the

clocktree network, RAM blocks, or digital signal processing (DSP) blocks.

The sub-total of the I

and power consumed by each architectural

feature is reported in each section in milli-Amps (mA) and milli-Watts

(mW).

The following sections of this user guide explain what values you need to

enter for each section of the PowerPlay early power estimator. Sections in

the PowerPlay early power estimator calculate power representing

architectural features of the device, such as clocks, RAM blocks, or DSP

blocks. Each section also provides an example of how you would enter

the relevant information into the PowerPlay early power estimator.

Device

Different Stratix

, Stratix GX, or Cyclone

™

devices consume different

amounts of power for the same design in a similar condition. The larger

the device, the more power it consumes because of the larger die and

longer interconnects in the device.

In the Device section of the PowerPlay early power estimator, select the

target device with the corresponding package and temperature grade

used in your design (Figure 3–1). The total power for both the logic array

and I/O pins are reported in this section.
