Temperature Information
The Temperature information control displays the temperature readings for the
FPGA and the board.
Power Information
The Power information control displays current, maximum, and minimum power
readings for the following unit:
■ mAmp
Power Graph
The power graph displays the mA 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.
The Clock Control
The Clock Control application sets the Si5338 programmable oscillator to any
frequency between 10 MHz and 810 MHz with eight digits of precision to the right of
the decimal point. The oscillator drives a 2-to-4 buffer that drives a copy of the clock
to all four edges of the FPGA.
The Clock Control application runs as a stand-alone application. ClockControl.exe
resides in the dir>\kits\stratixVGX_5sgxea7nf45_100g\examples\board_test_system directory.
On Windows, click Start > All Programs > Altera > Stratix V GX 100G Development
Kit
<version> > Clock Control to start the application.
