The third part was published:

In the second article about our GitHub study we analyzed the popularity of standard verification frameworks in VHDL repositories. This time we extend on those findings by analyzing the Git history of those repositories to find the number of users and examine how that changed over time.

Looking at users rather than repositories doesn’t have a drastic effect to the overall picture. VUnit is still the most commonly used verification framework on GitHub. However, when separating professional and academic users we’re starting to see interesting differences and anomalies in the data.

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.
