Power Estimation Using the PowerPlay Early Power Estimator

December 2010 Altera Corporation PowerPlay Early Power Estimator for Altera CPLDs User Guide

Power

This section describes the power dissipated in the MAX II and MAX V devices. The

total thermal power is shown in mWatts and is a sum of the thermal power of all the

resources being used in the device.

Tab le 2–2 lists the thermal power parameters in the PowerPlay EPE spreadsheet, as

shown in Figure 2–1 on page 2–1.

Table 2–2. Power Section Information

Column Heading Description

Clocks

Represents the dynamic power consumed by the clock networks. To view the details, click

Clocks.

Logic

Represents the dynamic power consumed by the logic elements (LEs) and associated routing. To

view the details, click Logic.

UFM Represents the dynamic power consumed by the UFM block. To view the details, click UFM.

I/O

Represents the dynamic power consumed by the I/O pins and associated routing. To view the

details, click I/O.

STANDBY

Represents the static power consumed irrespective of the clock frequency. The value includes

static power consumed by the I/O banks and the voltage regulator.

STANDBY

depends on the device you select and the V

CCINT

supply voltage.

TOTAL

Represents the total power consumed by the CPLD device. For more information about the

current draw from the CPLD supply rails, refer to “Power Supply Current” on page 2–5.
