For those of us who have been in the EDA business on one side or the other (or both), the Design Automation Conference (DAC) is one of the highlights of every year. I almost hate to admit it, but this year holds DAC number 29 for me. I’ve been to San Francisco, San Diego, Los Angeles, Anaheim, Las Vegas, Dallas, New Orleans, and Orlando, most of them multiple times. But one of the most fun locations was Austin, where DAC was held for the first time three years ago, and where we will return in just a few short months.
There will be plenty of time later for us to fill you in on what Breker will be doing at DAC this year. Since the program for the 53rd annual conference just went live, I thought I’d share some initial impressions and predict some likely highlights. Of course as an exhibitor I’m already deep in planning for the show, but I encourage all of you to review the program and start making your own plans. You’ll be sure to have lots of fun in Austin, and on the basis of the information available today I’m sure that this will be a great show.

Last week, we used an update on the Accellera Portable Stimulus Working Group (PSWG) presented at the Design and Verification Conference and Exhibition (DVCon) as a jumping-off point to discuss the status of this standardization effort and some key aspects of the three proposals currently under consideration. We were not the only blog to cover portable stimulus topics from DVCon; Brian Bailey of SemiconductorEngineering and Bernard Murphy from SemiWiki also posted their observations.
Earlier this week, EDACafe blogger colleague Peggy Aycinena posted a thought-provoking look at PSWG and the portable stimulus challenge. In regards to the scope of the proposed standard, she noted “a distinct wow factor in all of this, it’s so comprehensive” and said “this whole effort seems massive to me.” Today we’d like to respond to Peggy’s comments and questions, noting both the challenges of a portable stimulus standard and the availability of a working solution today.

As all of our regular readers are aware, the software-driven SoC verification space pioneered by Breker is becoming more of a mainstream approach every day. One good barometer for the industry shift now underway is the standardization effort in progress within the Accellera Portable Stimulus Working Group (PSWG). The amount of interest in this standard has skyrocketed recently, and portable stimulus was a hot topic at the Design and Verification Conference and Exhibition (DVCon) two weeks ago.
As we promised when we first began discussing the PSWG, we don’t believe in sharing internal details of standardization work in a public blog. However, the group was offered a slot to present an update at an Accellera-sponsored lunch during DVCon. So the PSWG put together a set of slides with information to share publicly and Vice-Chair Tom Fitzpatrick of Mentor did a nice job of presenting them. For those of you who could not attend, we’ll summarize the current status in today’s blog post.

In last week’s post on The Breker Trekker we summarized activities at the Design and Verification Conference and Exhibition (DVCon) in San Jose, including a brief mention of the “Redefining ESL” panel on Wednesday morning. I attended this session and took detailed notes in anticipation of blogging about it, but in the process gave some thought to my own opinions about the electronic system-level (ESL) domain and how they intersect with those of the panel participants.
The panel was organized by Dave Kelf of OneSpin Solutions and PR guru Nanette Collins, and moderated by Brian Bailey of SemiconductorEngineering. Brian is a long-time observer of the ESL market so I expected him to ask some tough questions. He opened by remarking that the term is generally credited to the late EDA analyst Gary Smith. Many of us who knew Gary sometimes teased him a bit on his regular pronouncements that “this will be the year of ESL.”

We’ve just returned from our most important trade show of the year: the Design and Verification Conference and Exhibition (DVCon) in San Jose. Sure, DAC is a bigger show, but it covers all of EDA and so lacks the front-end digital focus of DVCon. We previewed the event over our last few blog posts and today we’d like to summarize what happened and make a prediction or two about how this particular DVCon will affect the industry.
The biggest news for us was that portable stimulus seemed to be on everyone’s lips this year. Many of the engineers who stopped by to visit our booth had heard the term and were aware that the Accellera Portable Stimulus Working Group (PSWG) is developing a standard. If they didn’t know what portable stimulus was, they almost surely knew by the end of the show.
