The PowerMonitor GUI has the following panes:
•
CurrentMonitor
—This pane displays the current and power measured on the VDD_REG,
VDDA_REG, VDDA25, and VDD25_DUT rails. It also displays total device power. The I/Os are
excluded.
•
VoltageMonitor
—This pane displays the present voltage on each voltage rail. It also displays the
maximum and minimum voltage measured on each voltage rail over the time period of the
PowerMonitor application.The
Voltage Rail
plot in the pane displays the voltage plot of the selected
rail as a blue line. The green and red lines in the plot represent the over-voltage (+3%) and under-
voltage (-3%) tolerance levels of that rail. After staring the PowerMonitor GUI, the voltage plot takes
minimum five seconds to plot the samples.
Note:
For more information about the recommended minimum and maximum operating voltage of each rail,
see the
Recommended Operating Conditions
section of
DS0141: PolarFire FPGA Datasheet
.
The PowerMonitor GUI has the following buttons:
•
Graph
—Click this button to view the power consumed by the VDD_REG, VDDA_REG, VDDA25,
and VDD25_DUT rails, and also the total device power.
•
Pie
—Click this button to view the percentage of power consumed by the VDD_REG, VDDA_REG,
VDDA25, and VDD25_DUT rails out of the total device power.
•
Show Log
—Click this button to view a file with all actions of the power monitoring program.
•
Power
—Click this button to power up or power down the board when pins 2 and 3 of
J4
jumper are
closed.
Note:
When pins 1 and 2 of
J4
jumper are closed, use the
SW1
switch to power up or power down the board.
