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…)

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:
As we discussed in last week’s post, the past two days we were busy with activities at SNUG Silicon Valley, the annual focus for all things Synopsys. On Monday we exhibited in the Designer Community Expo, which drew programmers, architects, and verification engineers in addition to hardware designers. We have always been impressed by the verification teams we meet at SNUG. They’re all working on hard projects and open to new ideas that will help them find more bugs more quickly.
We also had the pleasure of speaking for the first time in the SNUG technical program, with a talk on “Integration of Portable Test Cases and System-Level Coverage with Verdi HW SW Debug Using VC Apps” in the VC Apps Developer Forum session yesterday. We had a nice response from the 65 or so attendees and were delighted with their interest. Since the talks in this session do not have corresponding papers in the SNUG Proceedings, we’d like to use today’s post to fill in the technical details.
Following a very successful DVCon in San Jose two weeks ago, next week we travel a few miles up the road to the Santa Clara Convention Center for the Synopsys Users Group (SNUG) Silicon Valley event. This will be our third year in a row exhibiting at this show, and it has become one of our favorites. We will also be speaking for the first time ever, and we’ll fill in all the details shortly. But let’s start by looking at why this show stands out and why we enjoy it so much.
SNUG actually has quite an interesting history. It began in 1991 as a way for Synopsys users to discuss common problems and solutions, meet with technical experts from the company’s R&D and AE teams, and learn about new products and features. Unlike many single-vendor conferences, SNUG has been driven largely by the users. They choose the papers to be presented and make many of the key decisions on how the event is run. Synopsys of course provides support in many ways.
In last week’s blog post on The Breker Treker we previewed this week’s Design and Verification Conference (DVCon) in San Jose, the leading industry event for verification professionals. We had a really good time there, finishing up just this afternoon. We always enjoy DVCon, but this week was even more fun than usual. We met attendees from an amazing range of companies designing SoCs, from simple microcontrollers to some of the largest FPGAs and custom chips on the planet.
Three aspects of the show really stood out: intense interest in cache coherency verification, considerable curiosity about the Accellera Portable Stimulus Working Group (PSWG), and the number of people who started the conversation with “I’ve heard good things about Breker from a colleague” or “I was told that I really need to check you out.” Let’s discuss what each of these trends means for the industry and speculate about the impact on Breker.
Most of the time when we blog about upcoming conferences, report live from an ongoing show, or summarize one that’s just finished, we see a significant spike in readership. Clearly our followers want to keep up with what’s happening in trade shows, conferences, and other industry events. It may also be the case that tighter travel budgets have reduced the ability to attend conferences in person, driving all the more interest in reading the news from the field. A few weeks ago, we discussed DesignCon and explained how it had evolved to include almost no verification content.
Next week is the annual Design and Verification Conference (DVCon) in San Jose, an event that we have covered in considerable detail in several popular posts in the past. As we have discussed, this conference has become the main way to keep up on what’s happening in the ever-changing world of functional verification. We encourage you to check out their Web site and the complete program. The topics include the UVM, SystemVerilog, SystemC, code generation, multi-language, mixed-signal, formal techniques, coverage metrics, and low-power verification.
In any industry dominated by a few large companies, it is important for the smaller players to ensure that their products work well with the broader solutions from the majors. Recognizing this need, and sometimes encouraged by legal action, the large companies develop partnership programs to enable and even foster integration with their solutions. All this is true for the EDA business, where the “Big 3″ work closely with many smaller vendors for the sake of their mutual customers.
In Breker’s case, we generate SoC test cases that run on a variety of software and hardware platforms. We do not build any of those platforms ourselves but we need to verify that our test cases can run properly on them. Accordingly, we are members of several important partnership programs and we work closely with other vendors to find and fix any interoperability issues before our customers run into them. In this week’s post, we focus on how we work with Synopsys, the EDA market leader.
One of the most popular posts in the history of The Breker Trekker was one discussing which conferences were most useful for verification engineers. I mentioned that Breker exhibited at the annual Design and Verification Conference (DVCon) in San Jose, and we’ve since published several popular posts about that show. It remains the most important event for us, our customers, and the functional verification industry in general. We will be there again in March, and will provide more information in an upcoming post.
I also mentioned the DesignCon show, held annually in Santa Clara, but did not list it among those that we attend. I always go and walk the floor for an hour or two to say hello to old friends and to see what’s new. However, Breker does not exhibit at this show and is highly unlikely to do so unless there are significant changes in its focus and attendance. This is not a criticism of the show, just an observation. Since DesignCon is happening this week, I thought that it might be fun to review its history and how it has changed.
Last year, we wound up in December with a post on the “Top 5 Holiday Gifts for the Verification Engineer” and it proved very popular despite the holiday timing. To refresh your memory (and ours), here is the 2013 list:
#5: Relief from hand-writing verification test code.
#4: Relief from hand-writing validation diagnostics.
#3: Vertical verification IP reuse from block to system.
#2: Horizontal verification IP reuse from electronic system level (ESL) to silicon.
#1: Effortless system coverage reflecting end-use applications.
As you might expect, every one of these gifts is still available today for users of our Trek family of products. But over the last year we have added two new products, many new features, and deeper integration into existing verification flows. So we’d like to wrap up 2014 with an all-new list of holiday gifts for the verification engineer. We hope you like them as much as you liked last year’s offerings:
In last week’s blog post, we talked about the emergence of the commercial IP industry and shared some personal experiences. Although Breker is an EDA company and not known for IP products, we intersect with semiconductor IP (SIP) and verification IP (VIP) in important ways as we work with our customers. We’re also starting to offer our own scenario model IP (SMIP) as part of accelerating and improving verification even more. We’d like to expand on these topics in today’s post.
We have few if any customers or prospective customers who don’t use commercial VIP in their testbenches. After all, if you’re designing a standard interface you want the best verification possible that you’re meeting the standard. A VIP model that’s been used by dozens or hundreds of other projects serves as a pre-silicon “plugfest” where you get to verify your implementation of the standard against what others have done. Now that the Universal Verification Methodology (UVM) is nearly ubiquitous, most VIP is developed in a fairly consistent manner.
