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…)

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
As some of you may have seen, two years ago the IEEE created an app that ranks the popularity of dozens of programming languages. They use twelve different metrics, from search results and social media mentions to technical publications and requirements listed in job openings. If you don’t like the way that they use these metrics, you can create your own ranking using your own mix. It’s really quite a clever idea and it generates lots of discussion every year.
For 2014 and 2015, C held the #2 spot, just below Java in the rankings. The big news this year is that C has edged into first place, although the top two spots remain very close as measured by the metrics the IEEE has chosen to use. C++ was in the #3 spot for the past two years, but for 2016 flipped places with Python. As you all know, we are strong advocates of C/C++ for verification and so we’d like to share some thoughts on these results and what they mean for our industry.
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.
We’re coming up to the two-and-a-half-year anniversary for The Breker Trekker, with 124 published posts. Initially I promised a post every other week, but after looking at the viewing patterns I quickly realized that I had to publish every week to establish a consistent audience. There’s always something to talk about in this fast-paced world, whether something new at Breker, standards activity, observations about the EDA industry, or analysis of the customers who drive our business.
Today I’d to acknowledge a second Breker blog that has actually been around longer than this one. Just over three years ago, Breker board of directors member Michel Courtoy started a series of posts in Electronic Engineering Times to offer advice to startups. He has published 28 such posts, and has covered an amazing amount of territory. I suppose that I should have done some “cross-promotion” earlier, but at this point I would like to highlight some of Michel’s sage advice. (more…)
For the most part, the terms “verification” and “validation” are used interchangeably in the electronics industry. However, there are many who argue that these are distinct activities in the development of SoC s and systems, performed at different times in the schedule and usually by different groups of engineers. We refer to ourselves as “The SoC Verification Company” and this is a deliberate choice we made. So we thought that it would be useful to define the two terms as we see them and talk about the similarities and differences.
This post was inspired by an article from 2010 that our CFO and co-founder Maheen Hamid discovered recently. It opens with the “usual definitions” as follows:
- “Validation: Are we building the right system?”
- “Verification: Are we building the system right?”
This seems like a good place to start the discussion.
Last week we discussed some of the drivers in the electronics industry influencing the program for the upcoming DVCon India, September 10-11 in Bangalore. The Technical Program Committee has completed its arduous task of selecting among many worthy proposals for sessions and has posted a near-final program. Today we’d like to highlight some of the most interesting aspects of the packed two days, focusing on sessions that we believe will be a particular draw for those who follow Breker and SoC verification.
There are four conference-wide keynote speeches, from Atul Bhatia (formerly of nSys), Harry Foster of Mentor, Manoj Gandhi of Synopsys, and Vinay Shenoy of Infineon. They will set the tone for the event by discussing the high-level challenges in designing and verifying leading-age semiconductor devices. Nick Heaton of Cadence will keynote the Design and Verification Track (DV) while Pankaj Singh of Infineon and Dr. Sacha Loitz of Continental will give invited talks in the Electronic System Level (ESL) track.
Many of our readers may recall that Breker aggressively promoted the inaugural DVCon India last year. We supported the show itself by sponsoring a booth in the exhibition and delivering three conference talks. It turned out, much to our delight, that that hottest topic at the show was portable stimulus. There was a great deal of interest in the newly formed Accellera Portable Stimulus Working Group (PSWG) and how Breker’s products provided a well-tested solution meeting all of the PSWG’s requirements.
The second DVCon India is less than a month away, on September 10-11 at Leela Palace in Bangalore. I have every expectation that portable stimulus will be a major theme again. We’re also very busy promoting the event to ensure its success, especially since I am co-chair of the Promotions Committee. I will be covering the details of the sessions and our own participation in next week’s blog post. For today, I’d like to focus on some of the industry drivers that are influencing the interest of potential attendees and the selection of content for the technical program.
One of the many challenges faced by small software companies is evolving their product lines in ways that make sense. New products must mesh with existing products so that customers can quickly understand what they might want. Products must be differentiated enough to stand separately, yet should leverage some of the same technology and expertise. Small companies have limited resources and it’s usually a mistake to develop multiple unrelated products requiring separate engineering teams.
Breker is no exception; we have a bunch of smart people with lots of ideas about how graphs can be applied to a wide range of problems. However, by focusing on the functional verification of large, complex chips using graph-based scenario models we are able to target a fairly specific group of companies and users. We also get tremendous productivity from a small R&D team because their collective knowledge spans the limited but important product range that we cover. This blog post is an attempt to describe that range more precisely.
