■ Power rail —Indicates the currently-selected power rail. The rotary switch (SW5)
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 information is available in the Stratix IV E 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
12-V Power Consumption
The 12-V 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.
