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 InnovationJanuary 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.

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. Read the rest of When Did CES Become the Chip Education Show? Revisiting System / Scenario / Use-Case CoverageJanuary 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 Read the rest of Revisiting System / Scenario / Use-Case Coverage Top 5 Latest Holiday Gifts for the Verification EngineerDecember 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. 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: Read the rest of Top 5 Latest Holiday Gifts for the Verification Engineer Frontiers of Microprocessor Test and VerificationDecember 22nd, 2015 by Tom Anderson, VP of Marketing
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.

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. Mystic Secrets of the Graph – Part ThreeDecember 10th, 2015 by Tom Anderson, VP of Marketing
The past two weeks, we’ve been having a bit of fun playing alchemist and letting readers in on some of the deep, dark secrets of graph-based verification technology. This week, we conclude the series by showing some additional capabilities for our scenario models that are easy to control and view in a graph visualization. Our point is, of course, that graphs are a natural way to represent data flow and verification intent with no advanced degrees from MIT, IIT, or Hogwarts required. As a quick reminder, graph-based scenario models begin with the end in mind and show all possible paths to create each possible outcome for the design. They look much like a reversed data-flow diagram, with outcomes on the left and inputs on the right. Breker’s Trek family can traverse the graph from left to right, randomizing selections to automatically generate test cases tailored to run in any target platform. Today, we continue using our example of a scenario model to verify that an automobile can move forward or stop. Mystic Secrets of the Graph – Part TwoDecember 3rd, 2015 by Tom Anderson, VP of Marketing
Last week, we began exploring some of the ancient, mysterious powers of graph-based scenario models to show their power for verification and ability to capture the verification space, many aspects of the verification plan, and critical coverage metrics. We’re just kidding about the first part; there’s nothing at all mystical or magical about graphs. In fact, this series of posts is intended to show the opposite and demonstrate with a easy-to-follow example the value of graphs. As we noted in our last post, graph-based scenario models are simple in concept: they begin with the end in mind and show all possible paths to create each possible outcome for the design. They look much like a reversed data-flow diagram, with outcomes on the left and inputs on the right. An automated tool such as Breker’s Trek family can traverse the graph from left to right, randomizing selections to generate test cases that can run in any target platform. Mystic Secrets of the Graph – Part OneNovember 24th, 2015 by Tom Anderson, VP of Marketing
If there’s one thing that Breker is known for, it’s the use of graphs for verification. From our earliest days, we harnessed the abstraction and expressive power of graph-based scenario models to capture the verification space, many aspects of the verification plan, and critical coverage metrics. As we reported in a post a few weeks ago, it looks certain that the industry will follow our lead and base the upcoming standard from Accellera‘s Portable Stimulus Working Group (PSWG) on a graph representation. As discussions have proceeded both within the PSWG and informally with interested parties, it has become clear that “graph” may not mean the same thing to all people. Our view of graphs is precisely defined in a way that makes it easy for users to create them and feasible for our tools to generated complex, multiprocessor test cases from them. Most of the key concepts can be communicated easily by the use of a familiar example, which we will begin in today’s post and continue next week. |
