WaveformViewer

Waveform viewer for Synopsys CustomCompiler, text table format, simulation data

Before usage

You will need:

• Python 3
• The bokeh ploting library (pip3 install bokeh --user)
• The pandas library (pip3 install pandas --user)
• The pillow library for PNG export (pip3 install pillow --user)
• The selenium library for PNG export (pip3 install selenium --user)

If you have problems related to phantomjs try the following:

• Install npm (apt install npm)
• Install phantomjs-prebuilt (npm install phantomjs-prebuilt)

Usage

• In a terminal, execute wp.py providing, at least, the required arguments (to see them see the help executing wv.py --help) to point to the data file, change the title, etc.

Examples

1. In a terminal, execute python3 wv.py or ./wv.py (if you changed the file to be executable). It will show you the help section.
2. wv -i <data_table> creates an HTML file with the plot for the given data_table and opens it in your default internet browser. Since no name for the output file is provided the same as the input is used.
3. wv -i <data_table> -o <image_from_data_table> same as before but now it saves the HTML file by the name image_from_data_table.html.
4. wv -i <data_table> -o <image_from_data_table> -dp same as before but now it saves the HTML file by the name image_from_data_table.html. The data points (actual simulated/calculated values) are also shown.
5. wv -i <data_table> -o <image_from_data_table> -dp -lw 2 same as before but changing the lines width.
6. wv -i <data_table> -o <image_from_data_table> -dp -lw 2 --no_output --save_png same as the previous one. The HTML file is not created, and also not shown. Finally a PNG file is created.

TODO

• Add support for batch file processing.
• Add option to export table.
• Change x axis notation to scientific (milli, micro, nano, etc.).
• Add some sort of verbosity.
• Add some sort of debug capability.
• Add the option of sourcing a local configuration file to have a consistent format for different plots.
• Add option to control the DPI output for the PNG output file.
• Add argument to control the axis ticks to db20.

DONE

• Use pandas dataframe to manipulate the data.
• Include support for multiple waveforms.
• Allow to mute the different plots pressing on its legends.
• Avoid showing the pandas dataframe on the terminal.
• Add argument to ask for an PNG output file.
• Add argument to ask for an SVG output file.
• Add argument to avoid showing the output, just to create the output file.
• Add argument to control the axis ticks to log.
• Add argument to change the axis labels.
