Test Interface
The test interface provides a quick and easy way
to verify many of the board's hardware circuits
and interfaces. Clicking Start Test will configure
the FPGA with test and PC-communication
circuits, overwriting any FPGA configuration that
may have been present. Once the indicator near
the Start Test button turns green, all available
tests can be run.
The Test RAM and Test Flash utilities write/read
data to/from all pages, ensuring the devices are
working properly and no signals have shorts or
opens.
The Test Shorts feature checks all discrete I/O’s
for shorts to Vdd, GND, and neighboring I/O pins.
The switches and buttons graphics show the
current states of those devices on the Genesys
board.
Future releases of Adept may add additional
tests, and more board features can be tested
using reference projects available on the Digilent
website.
Power
The power application provides highly-accurate
(better than 1%) real-time voltage, current, and
power readings from four on-board TI power-
supply monitors. The monitors are based on the
TI INA219 high-side current and power monitors,
which are configured to return 16-bit samples for
each channel at 16Hz, with each returned sample
being the average of 128 sub-samples. A 5mOhm
shunt resistor and selected INA219 gain setting
provide 4mV and 2mA measurement resolution.
Real-time voltage, current, and power data is
displayed in tabular form and updated
continuously when the power meter is active (or
started).
Historical data is available using the Show Graph
feature, which shows a graph with voltage,
current, and power plots for all four power
