The second article/chapter was published:

In the first article about our GitHub study we focused on the presence of tests in HDL repositories. This time we’re looking into what standard verification frameworks are being used. The main conclusions are that:

• VUnit is the most used verification framework for professional and academic VHDL repositories on GitHub.
• Most repositories using more than one framework use VUnit and OSVVM.
• More than half of the repositories using OSVVM also use VUnit.
• UVM is not combined with any other framework.

The full story and the code used to derive these facts are part of an open science project. Everything can be reviewed and the results can be repeated. We encourage contributions and suggestions on other interesting facts that we should derive.
