The Power Monitor

March 2014 Altera Corporation Stratix IV GX FPGA Development Kit User Guide

■ Power rail—Indicates the currently-selected power rail. The rotary switch (SW2)

on your board controls which rail to measure. After setting the switch for the

desired rail, click Reset to refresh the screen with new board readings.

f A table with the power rail switch positions is available in the Stratix IV GX

FPGA Development Board Reference Manual.

Temperature Information

The Temperature information controls display the following temperature readings

for the board and the FPGA on the board:

■ FPGA—Indicates the temperature of the FPGA device.

■ Board—Indicates the overall board temperature.

Power Information

The Power information control displays current, maximum, and minimum power

readings for the following units:

■ mVolt

■ mAmp

■ mWatt

12V Power Consumption

The 12V Power consumption control displays 12-V power consumption readings for

the following units:

■ mA

■ mW

Power Graph

The power graph displays the mWatt power consumption of your board over time.

The green line indicates the current value. The red line indicates the maximum value

read since the last reset. The yellow line indicates the minimum value read since the

last reset.

Graph Settings

The following Graph settings controls allow you to define the look and feel of the

power graph:

■ Scale select—Specifies the amount to scale the power graph. Select a smaller

number to zoom in to see finer detail. Select a larger number to zoom out to see the

entire range of recorded values.

■ Update speed—Specifies how often to refresh the graph.

Reset

This Reset control clears the graph, resets the minimum and maximum values, and

restarts the Power Monitor.
