Portable Stimulus Gains Momentum

Thursday, August 24th, 2017

Next month will see a significant milestone for Portable Stimulus. On September 15th the review period for the Early Adopter release of the Accellera Portable Stimulus Standard (PSS) will close and with it the opportunity to make your voice heard. This is an exciting time for Breker, the market leader in this space for the past decade, and signals a time when the industry can transition from a technology only available to a few aggressive adopters, to making it available to the mainstream.

Portable Stimulus – The First Verification Model

Tuesday, April 4th, 2017

When people think about design languages, they may not realize that the language is almost irrelevant. The language supports the underlying semantic model and it is this model that is important. EDA has defined design models at the gate level, the register transfer level (RTL) and various forms of behavioral levels. When we talk about RTL, we think about Verilog and VHDL, but they are only the languages that support that model, or very minor variations of it. But what about verification? (more…)

Users Talk Back on Portable Stimulus

Friday, March 17th, 2017

At the recent DVCon, I had the pleasure to moderate a panel that enabled users to talk about their experiences working with the Accellera standard’s body during the creation of the Portable Stimulus standard. I would like to thank Accellera for enabling such a panel and to Nanette Collins for organizing the panel and making sure that I had the easiest role in the ensuing discussion. I am sure that full write-ups of the panel will emerge, but I wanted to make the voice of the users heard. (more…)

Constrain Me, Please

Thursday, December 8th, 2016

In the movies, when a person acts irrationally they are usually declared to be mad and quickly placed in a straitjacket for the protection of themselves and those around them. If we continue those thoughts into the world of verification, SystemVerilog must be declared to be a mad language. (more…)

EDA Hates C++. Wait, What – Back Up!

Why is Accellera supporting the use of an industry standard language in the development of the Portable Stimulus Standard? (more…)

The Genesis of Portable Stimulus

Tuesday, October 25th, 2016

When I first met Adnan Hamid, Breker’s CEO, his philosophical understanding of verification and its implications for electronics was as crystal clear then as it is now. He sees it as the enabler for greater innovation in chips and beyond, and takes it as his life’s mission. His passion was inspiring to me and I did not hesitate for a second when we decided to jointly start Breker. Throughout our journey, I have watched the market converge with what we are building at Breker, and have come to better appreciate my partner, the visionary man. (more…)

The Next Wave in Verification

Thursday, September 29th, 2016

There is an important standard being worked on within Accellera and given its name, you might think that this is another incremental standard on a somewhat tired theme. It is called Portable Stimulus and yet it has almost nothing to do with stimulus and that stimulus, once generated by a tool not defined in the standard, is most certainly not portable. It is a fundamentally new approach to verification that could transform how chips and low-level software are verified. We will get back to the name in a moment, but the important thing is that users become informed about this new language and choose to have their voices heard in the standardization effort.

User Victory in Portable Stimulus

Thursday, September 8th, 2016

As regular readers know, the Portable Stimulus Working Group (PSWG) of the Accellera System Initiative has been working for some time to develop a new way to define verification intent once and to be able to reuse that across all stages of the verification flow and to be able to reuse it across designs. This will dramatically increase verification efficiency and establish verification methodologies that are likely to be used for the next couple of decades. (more…)

A Further Preview of DVCon India 2016

Wednesday, August 24th, 2016

Three weeks ago, we published a post on The Breker Trekker blog that previewed some of the talks and tutorials on the technical program at the upcoming third Design and Verification Conference and Exhibition (DVCon) India on September 15-16 in Bangalore. More of the details on the conference are now available online, and for today we’d like to highlight some of the keynote addresses, panels, and poster sessions on the agenda that also stand out for us.

As always, the program and steering committees have put a lot of thought into keynote speakers who will take a wide view of not just the EDA industry, but the larger electronics industry that we serve. Mentor CEO Wally Rhines is always a great speaker who comes armed with lots of charts and statistics to support his positions. His talk on “Design Verification: Challenging Yesterday, Today and Tomorrow” will survey the history and evolution of verification while predicting some of the future challenges

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.
