PowerPlay Early Power Estimator Input Values

Figure 3–2

shows a screen shot of the Global & Other Fast Signals report

from the Quartus II software Compilation Report. The report shows
fan-out for each signal that uses a global clock. The Timing Analysis
section of the Compilation Report lists the clock signal frequencies. Enter
the appropriate information from the Compilation Report into the
PowerPlay early power estimator.

Figure 3–3

shows the Stratix device

PowerPlay early power estimator and the estimated power consumed by
the global clock, regional clock, and fast regional clock networks for this
design.

and number of flip-flops you

entered. This value is estimated automatically.

Note to

Table 3–1

This value is limited by the number of blocks (DSP, M4K, M512, or MRAM) available in the largest device in the
family. You should verify that the number of (DSP, M4K, M512, or MRAM) blocks entered does not exceed the
number of (DSP, M4K, M512, or MRAM) blocks available in your target device because the PowerPlay early power
estimator does not verify this.
