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

DVCon India Just Keeps Getting Better

Wednesday, August 3rd, 2016

As many of you know, in 2014 the longstanding Design and Verification Conference and Exhibition (DVCon) expanded beyond Silicon Valley to India. The first year of DVCon India was very successful for a new event, drawing more than 450 attendees from more than 80 companies and universities. Last year’s show grew to more than 600 engineers attending the technical program, visiting the vendor exhibition, and enjoying the numerous opportunities to network with their peers.

The third annual DVCon India will be held on September 15 and 16, once again at the Leela Palace in Bangalore. From our perspective, the show just keeps getting better and better every year. The full program is now available online, and for today’s post we’d like to mention some of the technical sessions that we think look especially interesting. In a future post, we’ll discuss other aspects of the program, including the keynote addresses.

Catching Up with Portable Stimulus

Tuesday, April 26th, 2016

Ever since Accellera started the Portable Stimulus Working Group (PSWG), this emerging technology has generated a lot of buzz both within the EDA industry and among our semiconductor and systems customers. As the pioneer in this technology we get a lot of questions about what portable stimulus is, why it is different from the Universal Verification Methodology (UVM) and other established approaches, and why anyone would need it.

We’ve devoted quite a few posts to this topic in The Brekker Treker blog, stretching back two years to when Accellera first set up a proposed working group (PWG) to survey the industry and decided whether standardization of portable stimulus was feasible and desirable. Given the many posts scattered throughout the past two years, we thought that we would take this opportunity to give readers new to this topic a guided tour of the information that we have available.

Designers and Verification Engineers: Living in Different Worlds Together

Tuesday, April 19th, 2016

As I discussed at last week, there are many different engineering roles involved in the development of a large, complex semiconductor device. The EDA industry attempts to serve nearly all of these groups, from the architects and product marketing engineers who dream up the new ideas to the technicians who test production parts on the factory floor. Today I’m focusing on the work of two of EDA’s most traditional customer bases: hardware designers and hardware verification engineers.

Perhaps I’d better explain my title. It comes from an old expression “we went to different schools together” that I remember hearing as a youngster. Sometimes this refers to two people who didn’t actually attend the same school but who are nevertheless longtime close friends. But I’ve also heard it used to refer to two people who did in fact go to school together but had very different experiences. This latter context is the one I have mind for design and verification engineers who work on the same project yet inhabit different worlds.

A Snapshot Update on the Accellera Portable Stimulus Effort

Wednesday, March 16th, 2016

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.

DVCon Panel: Trying to Define the ESL Shapeshifter

Wednesday, March 9th, 2016

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.”

Portable Stimulus Was Front and Center at this Year’s DVCon

Thursday, March 3rd, 2016

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.

Automatically Generating Interacting, Self-Checking Test Cases for 144 CPU Cores

Wednesday, February 24th, 2016

We hope that the title of this blog post piqued your interest, because we don’t believe that we’ve seen anyone anywhere claiming to do automated multi-SoC verification at this level. Two weeks ago, we previewed next week’s Design and Verification Conference and Exhibition (DVCon) in San Jose. We highlighted one particular talk being co-presented by Breker and Cavium on “Using Portable Stimulus to Verify Cache Coherency in a Many-Core SoC” in the 9:00-10:30 a.m. session on Tuesday, March 1.

We teased you with the statement that this talk will describe “generating test cases for a multi-SoC configuration with well over 100 cores” and it’s time to tell you a bit more now that we have issued a press release on our project with Cavium. Of course, we need to reserve some of the details for the paper in the DVCon proceedings and the talk itself so that new material is being presented at the conference. We heartily encourage you at attend the show and hear for yourself.

Why Is Cache Coherency So Hard to Verify?

Friday, February 19th, 2016

In last week’s post, we provided a preview of the program at the annual Design and Verification Conference and Exhibition (DVCon) in San Jose, coming up in ten days. We mentioned some of the interesting talks and other activities there, and focused in particular on “Using Portable Stimulus to Verify Cache Coherency in a Many-Core SoC” on Tuesday morning. The paper for this session was co-authored by Breker and Cavium, and both companies will present together at DVCon.

The paper and presentation describe the use of our Cache Coherency TrekApp and TrekSoC-Si to automatically generate self-checking, portable test cases for more than 100 CPU cores in a multi-SoC configuration in the Cavium bring-up lab. To set the stage for this story, today we’d like to revisit some of the reasons why cache coherency is so hard to verify and why an automated approach is the best solution.

A Preview of the Upcoming DVCon in San Jose

Wednesday, February 10th, 2016

Regular readers of The Breker Trekker know that we like to preview, review, and dissect technical conferences and trade shows that are of interest to verification engineers. Perhaps the conference we’ve covered the most has been the annual Design and Verification Conference and Exhibition (DVCon) in San Jose. As far as we know, this is the biggest event anywhere focused on digital and system design and verification, a nice complement to the analog-ish DesignCon.

As a matter of fact, DVCon has become so successful that there are now regional conferences in India and Europe in addition to the U.S. show. We’ve strongly supported DVCon India, including serving for all three years on the Promotions Committee, and have participated in DVCon Europe as well. But those are a bit in the future; DVCon (U.S.) 2016 is coming up in a just a few weeks. The program is online now, so we thought we’d review it and suggest some sessions of possible interest.
