Story

Introduction

This project describes how to read the PMBUS metrics on the following Avnet platforms:

This guide provides instructions on how to read the PMBUS metrics on the following Avnet Vitis 2020.1 platforms:

Ultra96-V2 Development Board
UltraZed-EV SOM (7EV) + FMC Carrier Card
UltraZed-EG SOM (3EG) + IO Carrier Card
UltraZed-EG SOM (3EG) + PCIEC Carrier Card

This project made use of the following Vitis-AI 1.2 designs as a starting point:

http://avnet.me/vitis-ai-1.2-project

Setup

The first requirement for this project is the lm-sensors package, which includes the "sensors" utility.

Here is an example output for the ULTRA96V2 board, using the Vitis-AI 1.2 design:

For the UZ3EG platforms, if you do not get any output with the "sensors" utility, ensure that the following two jumpers are installed on the SOM:

PMBUS SCL
PMBUS SDA

The python scripts used in this project make use of the "PySensors" and "matplotlib" packages, which need to be installed as follows:

pip3 install pysensors
pip3 install matplotlib

If you get an error when running pip3 install, this could be caused by any or both of the following two causes:

invalid ethernet connection (refer to the board's Getting Started Guide)
invalid date (use the "date" command, as described below)

To configure a valid date use the following command:

$ date MMDDHHMM

where MMDDHHMM should correspond to the current month/day/hour/minute.

Running the Scripts

Before running the scripts, ensure that the DISPLAY environment variable is declared:

$ export DISPLAY=:0.0

The scripts can be run generically as follows:

$ python3 pmbus_plot_power_bars.py

The scripts can be run with ULTRA96V2 specific labels as follows:

$ python3 pmbus_plot_power_bars.py -t ULTRA96V2 -m 10000

The scripts can be run with UZ7EV_EVCC specific labels as follows:

$ python3 pmbus_plot_power_bars.py -t UZ7EV_EVCC -m 15000

The scripts can be run with UZ3EG_IOCC specific labels as follows:

$ python3 pmbus_plot_power_bars.py -t UZ3EG_IOCC -m 5000

The scripts can be run with UZ3EG_PCIEC specific labels as follows:

$ python3 pmbus_plot_power_bars.py -t UZ3EG_PCIEC -m 5000

The previous animated GIFs contain a video that was accelerated 4x, which ran for a 45 second period, during which the middle 30 seconds ran the resnet50 performance application as follows:

$ cd ~/Vitis-AI/vitis_ai_library/samples/classification/
$ ./test_performance_classification resnet50 ./test_performance_classification.list

Known Issues

In the scripts, I am not calling the plt.show(). Instead, I have used an alternate (less efficient) method, which converts the matplotlib canvas to a BGR image, which is then displayed with OpenCV's cv.imshow() function.

The scripts should probably be using matplotlib's animate functionnality. If anyone knows how to do this, please share your knowledge :)

Conclusion

I hope this tutorial was helpful to you.

If there is anything else you would like to see implemented, or if you have a more efficient implementation, please share your knowledge with the community.
