Last May, I published two blog posts on the presentations made at a “Decoding Formal Club” event hosted by the smart folks from Oski Technology at the Computer History Museum in Mountain View. With everything else going on, I didn’t manage to make it to another of their regular meetings until last week. The first event of 2015 was very interesting, so again I’m returning to the popular topic of formal analysis and playing reporter. The line between media and blogging is rather thin these days anyway.
This edition of Decoding Formal featured three talks, one an end-user case study and the other two instructional in nature from well-known formal experts. I found all three worthwhile and will do my best to communicate some of the main points made. I also have to mention the final presentation, more a performance than a talk, by the inimitable and irrepressible Clifford Stoll. Lately he’s been manufacturing and selling Klein bottles, which you may remember from a geometry teacher trying to mess with your mind.

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.

As you may have seen this morning, the EDA standards organization Accellera officially announced the formation of the Portable Stimulus Working Group (PSWG). This group has the charter to “develop the electronic industry’s first standard for portable test and stimulus. When completed and adopted, this standard will enable a single specification that will be portable from IP to full system and across multiple target implementations.”
Regular readers will note that this wording sounds very familiar. At Breker, we’ve been talking about vertical reuse from IP to SoC and horizontal reuse across all verification platforms for years. At times we’ve felt like pioneers with arrows in our back. The formation of the PSWG is a validation that we’ve been heading in the right direction. We’re excited to see the industry embracing the challenges of SoC verification and starting to work on a new standard to address these challenges.

I spent Tuesday of this week in the Winchester Mystery House, San Jose’s best-known tourist attraction, hearing a wide variety of opinions about design IP, verification IP (VIP), the Internet of Things (IoT), and related topics. “Unlock the Mystery of IP: Silicon Valley IP Users Conference” was organized and presented by IPextreme and their Constellations program partners. I found most of the talks quite interesting, and would like to share some thoughts on what the experts’ projections might mean for Breker and our customers.
There is no doubt that the increasing use of IP is key to designing ever larger chips. Kands Manickam of IPextreme noted that, over the next five years, the compound annual growth rate (CAGR) of IP blocks and subsystems is expected to be 12% versus 3.5% for semiconductors. Randy Smith of Sonics reported that the average large chip today has about 120 blocks, growing to more than 200 by 2018. We already know that VIP reuse is not as effective as design IP reuse, and these projections will only exacerbate the gap.

Last week we summarized some of the activities at the inaugural DVCon India. Breker was not the only company impressed by this show. For example, CVC wrote two posts on their VerifNews blog describing the excitement and range of technical content at the show. Gaurav Jalan captured several aspects of the show in his Sid’dha-karana blog, focusing specifically on the keynote speakers. The Agnisys blog also provided a nice overview. Clearly this was a very successful event.
The high quality of the technical content and the excellent attendance at DVCon lead me to think about how much India has changed in just a few years. I first had an engineering team there in 1995, nearly 20 years ago. I recall my first trip to India very well and the contrast with recent visits is tremendous. I’ve been deeply impressed by the evolution of electronics development in India and I see the DVCon success as both a tribute to where the community is today and a sign of even better things to come.

Over the last several blogs posts, we’ve twice previewed the very first DVCon India show, celebrating it as a sign of India’s ever-growing importance in the electronics industry. We also mentioned that our co-founder and CEO Adnan Hamid would be presenting in two tutorials and helping to staff our booth in the exhibition. Now that the event is over and Adnan has returned from his travels, we’d like to fill you in what turned out to be a great event.
We have heard nothing but positive comments from attendees, vendors, and organizers. The conference was well attended, full of strong technical content, and well run. Perhaps the dominant theme to emerge was the importance of the “portable stimulus” effort undertaken by Accellera and the solutions available to meet some or all of the vision. It may be a stretch to call DVCon India the “Portable Stimulus Conference” but surely the first day (Thursday) was “Portable Stimulus Day” and we’ll explain why.

What verification engineer doesn’t love the occasional conference? It’s a chance to get out of the cubicle farm, hang out with colleagues from other companies, listen to stimulating technical talks, and catch up on what EDA, IP, and semiconductor vendors have been doing. Even in a time of tight travel budgets, the right conference can provide dividends far beyond its cost. There are a lot of smart people in the electronics industry and it’s valuable to share problems and solutions with them.
There are actually quite a few conferences and trade shows that have interesting verification content and draw significant numbers of verification engineers. One of the most-read posts in the history of The Breker Trekker blog was a discussion on which conferences verification engineers like best. We are constantly evaluating which events provide the most value to us and our customers, and find ourselves in the unusual position of having four shows scheduled in four locations over the next four weeks.

As anyone involved in chip development knows, one of the biggest events of the year is the Design and Verification Conference and Exhibition, DVCon, which has been held for many years in San Jose. I’ve frequently shared my thoughts on this show and its importance to the industry in this blog. In just four weeks, DVCon expands to Bangalore for the very first DVCon India show. The full program for September 25-26 is now online and I’d like to focus on a few highlights from my perspective.
The first thing to note is the breadth of material being covered. The technical track is split between electronic system level (ESL) and design and verification (DV) topics, with a slight edge to the latter in terms of overall sessions. There are as many as five tracks in parallel, which is quite an accomplishment for a brand-new event. I know that there were many excellent session proposals submitted, which means that those selected are likely to be of high quality and wide interest.
