Is SVUnit a legit verification framework?
I get that question periodically from folks who are looking into incorporating SVUnit into their verification flow. Of course it’s always phrased a little differently depending on who’s asking – How many users are there? What is the bug rate? What teams have integrated it into their verification flow? Have people published papers about it? Is it actively being developed? Do others contribute to the development? – but the intent behind the question always feels the same. We developers want to know that others have blazed the trail before us, that the tools we’re considering have a proven track record, that the major bugs and issues are long since fixed and that tools are truly ready before we get started with them.

That said, I’m confident we have enough anecdotal evidence for a solid yes. SVUnit is a legitimate test framework for design and verification engineers looking for an alternative that addresses low level code quality.
Here’s a few stats to support that yes: Continue reading
