Over the last couple of decades, vendor-specific conferences have complemented and in some markets even supplanted general industry events. Intel, Microsoft, Sun/Oracle, Apple, and many other companies have had huge, successful shows year after year. Perhaps it’s a sign of a certain level of maturity when a company has the resources to hold its own event and the appeal to attract a large crowd.
In the world of EDA (and IP, and embedded systems), ARM is certainly one of the biggest recent success stories. As the company has grown, its small technical events have evolved into a major show now known as ARM TechCon. Breker will be both speaking and exhibiting at this week’s event in Santa Clara, just down the road from Breker’s headquarters in San Jose.

Breker customers have surely noticed that the quantity and quality of our product documentation have taken a huge leap in the last six months or so. This is due to the Herculean efforts of Bob Widman, a well-known documentation, training, and applications expert in the EDA industry. He has been working with Breker for most of this year and the results speak for themselves. We’re pleased that Bob has contributed the following guest post on the importance of documentation:
Why does a company provide documentation with its product? The typical answer is that the customer expects it. Often overlooked is how the process of creating the documentation has a positive impact on the product and the company that is developing it.

All of us at Breker are excited as we write this post, since we’ve just made our most important product announcement in several years. We’ve expanded the Breker product line by adding TrekSoC-Si, a brand-new tool that generates multi-threaded, multi-processor, self-verifying C test cases for in-circuit emulation (ICE), FPGA-based prototypes, and actual production silicon. In other words, TrekSoC-Si does for hardware platforms what TrekSoC did for simulation.
We’ll talk more about how TrekSoC-Si works in a moment. But first it’s important to note that both TrekSoC and TrekSoC-Si use the same graph-based scenario models as input to describe the intended behavior of the SoC and provide a test plan. This means that, for the first time in the industry, you can achieve horizontal verification reuse across your entire project schedule, from high-level simulation models all the way through your first chips arriving from the foundry.

One of the curious aspects of electronics is that most products are specified from the top down but implemented and verified from the bottom up. This is true for system-on-chip (SoC) development as well. As the onset, someone in product marketing specifies a chip that has a specific collection of functionality to meet a specific customer need. The architecture team develops a block diagram that defines the subsystems and perhaps some individual IP blocks as well.
When it comes time to develop the RTL that implements the SoC, designers tend to work from the IP blocks upward. They select commercial IP where it makes sense and develop unique IP when needed. Designers are usually responsible for verifying their own blocks, perhaps with some assistance from verification engineers. There is usually minimal verification of commercial IP unless it has been customized for the SoC project.

Last week our friends at Cadence held the grandly named System-to-Silicon Summit not in some grand hotel, but rather at their San Jose offices. While Breker folks of course were not invited, we were curious as to how much SoC verification was addressed. Fortunately, Cadence writer and EDA legend Richard Goering has provided a very nice summary of a panel at the event dealing very much with topics of interest to us and our customers.
Within three paragraphs of Richard’s article, journalist Brian Bailey is already talking about top-down verification with “use cases.” Cadence’s Ziv Binyamini continued the topic by saying “the only way to define the requirements is against the use cases.” Jim Hogan mentioned “scenarios” for defining system behavior. There was also discussion about use cases being valuable for embedded software as well as hardware. To anyone who knows anything about Breker, this all sounds very familiar.

I had planned to write today about the TrekBox module, an essential part of TrekSoC that links the code running in the embedded processors with the I/O pins of an SoC. But, in the course of reviewing my various daily news digests, I read the curiously titled blog post “Tightlipped Unicorns & Monochrome Rainbows” on the Electronic Engineering Times site. It moved my thoughts in other directions entirely, so here is the result.
In the post, Radfan CTO Simon Barker argues that startups should be more honest about the challenges they face in order to obtain help or advice from those who’ve already lived through such adventures. He maintains that company founders who automatically say “Great!” when asked how things are going are missing an opportunity to garner such assistance and are wasting their time at startup events. This position triggered three major lines of thought for me.

A notice about “early bird” registration for the 11th International System-on-Chip (SoC) Conference, Exhibit, and Workshops arrived in my inbox late last week. It reminded me that this event is coming up quickly (October 23-24) and that, among other things, I’d better get my slides done in time to make it into the Proceedings. My talk is called “The Search for a Truly Unified Verification Methodology” and it will be on the second day at 4:05pm.
If you look at the program, you’ll quickly see that this is one of the most diverse conferences of the year. A wide variety of experts from both academia and the commercial world considers SOC development from many different angles. One minute you may be listening to a talk on high-level system performance measurement, and the next on the silicon structures for a new type of on-chip memory array.

In our last technical blog post, we surveyed some of the existing forms of coverage, including their virtues and limitations, and their applicability to SoC designs. We also introduced a new type of metric, system coverage, based on application scenarios that reflect how an end user would actually run applications on the SoC. We closed by claiming that “Breker’s graph-based scenario models are ideal for establishing, measuring, and refining system coverage.” This is the next in a series of posts to explain why and how.
Another earlier post described the Breker approach of “beginning with the end in mind” using graph-based scenario models. In the graphs used by TrekSoC, outcomes appear on the left and inputs appear on the right, reflecting the way that the test case generator works from the desired result toward the setup conditions needed for a particular application scenario.

In just a week, my last post has become the most-read since we launched The Breker Trekker blog. That’s fine with me; beneath the intentionally provocative title I had some serious observations on how the EDA industry has evolved over the last couple of decades. My thought for the week is “never underestimate the power of zombies to grab people’s interest.” Mentioning zombies make me think of vampires, since the two are so intertwined in popular culture. There are lots of articles on why we’re so fascinated with these two creatures, and what it means when one is more popular than the other.
I’ll bet that most of you are running ahead of me now and thinking, “Vampires? This must be Breker’s column about venture capitalists.” Indeed this is a post about investors and their role in the formation and fate of EDA companies. Sure, some venture capitalists (VCs) might be viewed as vampires or vultures. But in my personal experience I’ve seen a wide range of investors with very different motivations and methods of interacting with their startups, most of them quite positive.

From the blog stats it seems clear that late August is a slow time with lots of folks on vacation, so I’ll take a break from the heavy technical topics to chat about the industry. Long before I worked for an EDA company, I was an active participant as a user of EDA tools and as a CAD manager tasked with evaluating them and integrating them together. In that role, I loved working with interesting startups that had new ideas for electronic development.
It was part of my job to follow the EDA industry closely so that we could choose our tool investments based on both strength of technology and likelihood of vendor success. It seemed to me that the industry was divided into only three categories: major leaguers, minor leaguers, and startups. I observed that nearly all EDA startups disappeared after three or four years, with three possible endgames: acquisition, initial public offering (IPO), or bankruptcy.
