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

 
March 3rd, 2016 by Tom Anderson, VP of Marketing

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

 
February 24th, 2016 by Tom Anderson, VP of Marketing

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?

 
February 19th, 2016 by Tom Anderson, VP of Marketing

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

 
February 10th, 2016 by Tom Anderson, VP of Marketing

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.

Expanding Our Scope to Multi-SoC System Verification

 
February 3rd, 2016 by Tom Anderson, VP of Marketing

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.

What Does Semi Merger Mania Mean for EDA?

 
January 27th, 2016 by Tom Anderson, VP of Marketing

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.

Silicon Valley Still a Center of Semiconductor Innovation

 
January 20th, 2016 by Tom Anderson, VP of Marketing

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.

When Did CES Become the Chip Education Show?

 
January 12th, 2016 by Tom Anderson, VP of Marketing

Last week the International Consumer Electronics Show returned to Las Vegas, where it has been a major event for nearly 40 years. Nearly everyone calls this show CES, to the extent that its home page doesn’t even tell you what the acronym means anymore. So CES it is, one of the largest and best-known technology-oriented conferences in the world. Its sheer size makes it a test of stamina for exhibitors and visitors alike.

When people think of CES, they think of wandering the aisles and being overwhelmed by all the cool products on display. From massive HDTV screens down to the smallest Internet of Things (IoT) devices, this show appears to have it all. It seems to me, however, that CES has evolved into an event that’s almost as much about the underlying silicon as it is above the consumer-oriented end products. I’d like to explore that idea in today’s post.

Revisiting System / Scenario / Use-Case Coverage

 
January 6th, 2016 by Tom Anderson, VP of Marketing

It’s been more than a year since we presented the Breker view of system coverage in detail, so it’s time to revisit the topic. We first defined the notion of system coverage as measuring which realistic, system-level application scenarios have been exercised using the existing test cases. We then demonstrated how our graph-based scenario models are ideally suited to capture system coverage metrics and fine-tune them using graph constraints if needed.

More recently, we noted that the term “use cases” has become more widespread and introduced the example of a digital camera SoC to show the types of use cases that should be exercised. The measurement for this exercise is also system coverage, so the bottom line is that all these terms are really talking about the same thing. Using a regular expression, we might say:

[application|realistic] (scenario|use-case) coverage = system coverage

Top 5 Latest Holiday Gifts for the Verification Engineer

 
December 30th, 2015 by Tom Anderson, VP of Marketing

It’s becoming somewhat of a tradition here on The Breker Trekker blog to close each year with a list of gifts available from us to verification engineers. We started the series two years ago with an initial list focusing on our core benefits of automatic test case generation, system coverage, and reuse both vertically (IP to system) and horizontally (simulation to silicon). Last year’s post offered five more gifts reflecting additional products and new features added to our overall solution:

#5: Easier sequence specification in UVM testbenches.
#4: Faster coverage closure in UVM testbenches.
#3: Integration of system coverage with other coverage metrics.
#2: Debug of automatic test cases using standard tools.
#1: A fully automated solution for cache coherency verification.

Every one of the ten gifts from 2013 and 2014 is still available today for our customers. In addition, we have continued to evolve our Trek family of products and to deploy it on ever more challenging SoC verification projects. Without further ado, here is our all-new list of holiday gifts for the verification engineer in 2015:
