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.

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.

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.

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.

For more than four years now, Breker has branded itself as “The SoC Verification Company” and many people acknowledge our expertise in this domain. As we have discussed before on The Breker Trekker, our initial products focused on generating purely transactional tests for a simulation testbench, usually compliant with the Accellera Universal Verification Methodology (UVM) standard. When we extended our products to generate C code that runs on the embedded processors found within SoCs, we delivered on our “tagline” promise.
Since our early focus on simulating an SoC, we have expanded our technology and our product line to generate C test cases that run on embedded processors in emulation, FPGA prototypes, and actual silicon in the bring-up lab. In talking about what we do, we struggle to choose between “SoC” and “system” since for many of our customers the terms are synonymous. But we also have users verifying multi-SoC systems, and today we’d like to address that topic.

Some of the highest readership here at The Breker Trekker happens when we post articles about the state of the semiconductor industry or EDA industry. It’s been a while since we looked inward at our own industry, but we have had a series of very popular posts about the ongoing changes in the semiconductor market, including the “merger mania” of the last few years. Although not all closed, in 2015 alone there were several dozen offers totaling well over US$150B.
Since semiconductor vendors are the main customers for EDA, with their customers the remainder of our market, we track both industries very closely. In last week’s post, we looked what the ongoing merger and acquisition (M&A) activity means for Silicon Valley. Our friend Graham Bell at Real Intent added a comment wondering about the impact of this M&A on the EDA industry. Today’s post contains some of our thoughts on this matter.

As someone who has lived in the heart of Silicon Valley for more than 30 years, I’m used to the regular cries that we’re losing our innovative edge. Every few years something happens to cast some doubt on our future: a stock market crash, a major company moving elsewhere, or a lot of press about some new Silicon Forest/Glen/Mountain/Prairie/Island/Whatever trying to beat us at our own game.
Sure, we face plenty of challenges. A recent article on SemiWiki painted a rather cautionary view of today’s Silicon Valley. But there’s good news too. Silicon “Valley” has grown to include San Francisco and much of the Bay area, with corresponding growth in technology employment and impact. Today, I’d like to springboard from a recent post on semiconductor mergers and acquisitions to consider one particular aspect of the current role of Silicon Valley.
