Frontiers of Microprocessor Test and Verification

Tuesday, December 22nd, 2015

In last week’s blog post, I reported from the recent 16th International Workshop on Microprocessor Test and Verification (MTV) in Austin. I focused mostly on the panel “Portable Stimulus and Testbenches – Possibilities or Wishful Thinking?” that included representatives from ARM, Cadence, Mentor, Synopsys, Freescale (now NXP), and Breker (yours truly). The panel was most enjoyable, but only one of several highlights for me at MTV.

This week, I’d like to touch briefly on some of the talks and topics on the technical program that caught my ear. These reflected a number of research frontiers for verification as well as several real-world case studies of SoC design projects tackling tough verification challenges. Perhaps the best moment for me was hearing Altera, one of our customers, describe how they used our products successfully on a recent design.


Report from the 16th MTV Workshop

Wednesday, December 16th, 2015

Do you want to hear all the behind-the-scenes dirt from a workshop on the future of the MTV cable channel? Well, you’ll have to look elsewhere. “MTV” in this case means the International Workshop on Microprocessor Test and Verification, which celebrated its 16th incarnation in Austin two weeks ago. Although the name of the workshop has officially expanded to “Microprocessor and SOC Test and Verification” rest assured that the delightfully ambiguous abbreviation “MTV” will remain.

This was only my second time at this event, but I wish that I had been able to attend more. The setting is the top floor of the Hyatt Regency, with great views of Lady Bird Lake (formerly Town Lake) and downtown Austin. However, I noticed that recent high-rise construction has now blocked the sight of the Texas State Capitol from the hotel. The view might be distracting if not for the fact that the technical committee put together an interesting and diverse program, including a panel on portable stimulus.


Invention Protection: Patently Obvious or Patently Absurd?

Tuesday, November 3rd, 2015

The long-established trade association EDA Consortium (EDAC) has started several new initiatives to extend its membership to IP suppliers and to offer more value to its members through new programs. New EDAC Director Bob Smith has a bunch of innovative ideas and I have little doubt that they will breathe new life into the organization. I had the pleasure of working with Bob when he did some consulting for Breker several years ago, and he’s a true professional.

Last week I attended the first in a series of legal-themed events sponsored by EDAC. I expected that the title “Patents and Patent Litigation: Develop, Strengthen, and Protect Your Intellectual Property” would draw well, and indeed the conference room at SEMI Global Headquarters in San Jose was packed. I won’t attempt to cover the wide range of topics addressed, but I would like to hit a few highlights from the panel discussion and the excellent questions from the moderator and the audience.


Merger Mania in the Semiconductor Industry

Wednesday, October 7th, 2015

Earlier this year, we published an analysis of the semiconductor landscape that became one of the most-read posts in the history of The Breker Trekker. That’s not too surprising, since business topics tend to have wider appeal than detailed discussions about verification techniques. That post focused on the top 20 semiconductor companies and the many changes in that list over the last 15 years. We mentioned a number of noteworthy mergers, acquisitions, and spin-outs that contributed significantly to the dynamic nature of the market.

The first three quarters of this year have seen a huge uptick in merger and acquisition (M&A) activity among semiconductor companies. Although many of these deals have involved second-tier players, at least a few are significant enough to result in changes to the next Top 20 listing. Since we follow the chip industry closely, we thought we’d summarize some of the recent announcements and speculate a bit on what it all means.


The Results Are In, and Graphs Win!

Friday, October 2nd, 2015

Anyone who has followed Breker for any length of time knows that our key technology is the ability to generate both Universal Verification Methodology (UVM) testbench transactions and C test cases running on SoC embedded processors automatically from graph-based scenario models. Yes, that’s a long sentence but it’s most of the “elevator pitch” that we might deliver to a potential investor or to a visitor at a trade show booth asking what we do.

For the purposes of today’s post, note that graphs are the root of the solution we provide. Ten years ago, when we first began talking about the idea of graphs as the basis for functional verification of complex chip designs, we were the proverbial pioneer with arrows in our back. But many successful customer engagements and the ever-rising need for better verification have validated our position. Graphs are clearly the “next big thing” in verification and we’d like to explain why.


There Is No Silver Bullet for Low-Power Verification

Wednesday, September 23rd, 2015

Anyone who reads The Breker Trekker from time to time needs no convincing from me that verification is a huge challenge for today’s complex chips. Breker’s Trek family of products exists, along with dozens if not hundreds of other EDA products, specifically to address functional verification. There are more technologies, tools, platforms, libraries, and methodologies than any one verification engineer can possibly learn and use on a day-to-day basis.

Why this diversity of solutions? As I first observed in Electronic Engineering Times nearly a decade ago, there is no silver bullet for verification. The problem is both so broad and so deep that no single tool or technology will ever satisfy the need. It takes a mix of solutions, guided by methodologies, to have any chance of first-silicon success. Low-power verification is an area where this is especially true, and unfortunately there is no silver bullet to be found here either.


Riding the Portable Stimulus Wave

Wednesday, September 16th, 2015

Last week, we discussed the details of a noteworthy press release that we issued with Cadence and Mentor Graphics announcing a joint contribution to the Portable Stimulus Working Group (PSWG) of Accellera Systems Initiative. As we expected, this release stirred up a lot of interest in portable stimulus. The timing was perfect, both because of today’s deadline for contributions to the PSWG and because of last week’s DVCon India conference. I’d like to provide some updates on both activities.

First of all, the three companies did upload our joint contribution document to the PSWG internal Web site today in time for the deadline. Please note that, as per the rules for Accellera and most other standards groups, working documents are not available to the general public. If you’d like to see the contribution and follow the evolution of the standard, please consider joining the PSWG. If your company is not yet a member of Accellera, then please alert your standards manager to the benefits of participation.


Breker, Cadence, and Mentor Accelerate Portable Stimulus Standard

Tuesday, September 8th, 2015

This morning, Breker issued a press release with Cadence and Mentor Graphics announcing a joint contribution to the Portable Stimulus Working Group (PSWG) of Accellera Systems Initiative. We expect that this news may be surprising to much of the EDA world, so we’d like to take today’s post on The Breker Trekker to fill in some background and offer you the opportunity to ask questions. Please note that we are speaking only for Breker in this post although we doubtless share many opinions with our co-contributors.

Let’s start with a quick summary of how Accellera works so that all readers understand the context for this major contribution. The portable stimulus effort started with a Proposed Working Group last year that assessed the interest in a standard and defined a set of more than 100 requirements that such a standard would have to satisfy. Accellera approved the formation of the PSWG and we began meeting in March of this year. We have refined the requirements list and also developed a set of “use cases” showing the sort of real-world verification problems that a standard would have to address.


The Second DVCon India Looks Even Better than the First

Thursday, August 20th, 2015

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.


Industry Drivers for DVCon India

Wednesday, August 12th, 2015

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.
