I expect that the activities of the EDA Consortium (EDAC), our industry’s main trade organization, are followed more closely by EDA vendors than users. However, some of you may have seen the recent publicity surrounding the organization’s name change to the Electronic System Design Alliance (ESDA). I applaud this move because it reflects the gradual but ongoing merger of EDA and embedded systems, a topic that we have covered here on The Breker Trekker in the past.
However, I do have two reservations about the specifics of the name change. First, as some people have pointed out, “ESD” is strongly associated with “electrostatic discharge” for us engineers who have worked on actual lab benches and not just in the world of abstract EDA models. But that’s a minor quibble as far as I’m concerned. My bigger issue is that EDAC did not use the name change as a chance to expand from “design” to “development” in its description of scope. Please continue reading as I expand a bit on all three of these points.

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…)

A month ago, our blog post on The Breker Trekker concerned life on the hardware-software frontier. We discussed the ever-shifting line between hardware and software and how we at Breker seem to be straddling that line as we generate embedded C/C++ test cases for hardware verification. Yesterday we published an article on the ongoing merger between the worlds of embedded systems and EDA. We made a number of observations about how the two industries are drawing closer together.
We didn’t talk about Breker in yesterday’s article, but today we’d like to connect these two threads and talk about how we are now straddling the increasingly fuzzy line between embedded and EDA verification. This is a topic we’ve discussed internally from time to time, and we have taken some steps into the embedded world by exhibiting at ARM TechCon and publishing articles in magazine and on sites geared toward embedded designers and programmers.

In last week’s post, we spent quite a bit of time talking about the concept of a (realistic) use case that reflected how actual users will eventually manipulate the design being verified. Our focus was on Breker’s graph-based scenario models and how they can easily and concisely capture such use cases. We did some research on the term “use case” and found that it seems to be more common in software design and verification than in hardware verification. That caused us to think about how we at Breker seem to be living on the hardware-software frontier.
It’s not uncommon for hardware designers and software engineers to borrow ideas from each other. Code coverage, for example, was well established in software before it was adopted for hardware design and verification languages. With the move from gates to RTL, hardware became just another form of code and therefore more amenable to software techniques. This is just one example showing that the boundary between hardware and software is fuzzy and changing over time.
