IEEE Reports that C is the Most Popular Programming Language

Wednesday, August 10th, 2016

As some of you may have seen, two years ago the IEEE created an app that ranks the popularity of dozens of programming languages. They use twelve different metrics, from search results and social media mentions to technical publications and requirements listed in job openings. If you don’t like the way¬† that they use these metrics, you can create your own ranking using your own mix. It’s really quite a clever idea and it generates lots of discussion every year.

For 2014 and 2015, C held the #2 spot, just below Java in the rankings. The big news this year is that C has edged into first place, although the top two spots remain very close as measured by the metrics the IEEE has chosen to use. C++ was in the #3 spot for the past two years, but for 2016 flipped places with Python. As you all know, we are strong advocates of C/C++ for verification and so we’d like to share some thoughts on these results and what they mean for our industry.


Why C/C++ Is the Lingua Franca for Verification

Tuesday, November 17th, 2015

In last week’s post, we dissected the results for verification languages and methodologies from a recent survey by Mentor Graphics and Wilson Research Group. The main result was that SystemVerilog is growing in popularity on all fronts, but we observed that C/C++ has a significant presence. We also argued that the survey’s focus on simulation likely resulted in C/C++ being under-represented since these languages are widely used for verification with hardware platforms and for silicon validation in the lab.

We see C/C++ as the common link for many types of programming activities, and so widely known that many consider it the lingua franca of software. Just type “lingua franca C/C++” into your favorite search engine and scan the results for some interesting arguments and a few counter-arguments. To be fair, some observers consider C the lingua franca and downplay C++. We tend to group them together since object-oriented programming is now widespread and so moving from C to C++ should be a natural transition.


Verification Languages: Tower of Babel?

Wednesday, November 11th, 2015

One of the cliches we hear from time to time in the industry is “designers want to stick with a single language, but verification engineers love learning new things.” The implication seems to be that because verification engineers have diverse jobs that require them to juggle lots of different tools and models, they necessarily have to learn new languages and methodologies on a regular basis. Of course, they may not actually love learning new languages; doing so may just be in the nature of their work.

Regardless of whether or not they “love” new languages, it is clear that most verification projects involve multiple languages and multiple approaches. One way to gauge the current situation is to turn to the excellent survey that Mentor Graphics performs with Wilson Research Group every couple of years. Harry Foster wrote a series of posts on the Mentor verification blog that give considerable insight into what verification (and design) engineers are doing on real projects.
