General Information

The General information controls display the following information about the

MAX II device:

■ MAX II Version—Indicates the version of MAX II code currently running on the

board. The MAX II code resides in the <install

dir>\kits\arriaIIGX_2agx125_fpga\factory_recovery and <install

dir>\kits\arriaIIGX_2agx125_fpga\examples\max2 directories. Newer revisions

of this code might be available on the Arria II GX FPGA Development Kit page of

the Altera website.

■ Power Rail—Selects the power rail to measure. After selecting 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 Arria II GX FPGA

Development Board Reference Manual.

Power Information

This control displays RMS current, maximum, and minimum power readings for the

following units:

■ mVolt

■ mAmp

■ mWatt

Power Graph

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

the Power Monitor.
