Generate SVD file from a reference manual

Generates an SVD file for the Silicon Labs SiM3U1x7 from the reference manual.

This is currently work in progress and in a early stage.

Detailed steps

First the sim3u reference manual must be downloaded into the doc folder:

wget -P doc/ https://www.silabs.com/documents/public/data-sheets/SiM3U1xx-SiM3C1xx-RM.pdf

Install the pipenv environment:

pipenv install

To execute the tool:

pipenv run python src/parse_sim3u.py --input doc/SiM3U1xx-SiM3C1xx-RM.pdf --out out.svd

Use helper script

Or instead of all of the above, execute:

./create_svd.sh

This might take half an hour, so be patient...

Flow

The script executes the following steps:

• read the toc/outtline of the pdf file
• read the peripheral overview
• read register information for all peripherals
  • this contains the registers and the description of the bits inside the registers
  • these information is attached to the corresponding peripheral

Current status

• svd file is created
• generation of header file from created svd works
• gpio and uart drivers based on the created svd are working
• Most enumeration value names are suboptimal
• most parts are untested

Info

This created svd file is intended to be used in the SiM3U port of Zephyr that is currently in development: https://github.com/chrta/zephyr-sim3u
