What Does Semi Merger Mania Mean for EDA?

Wednesday, January 27th, 2016

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 Innovation

Wednesday, January 20th, 2016

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.


When Did CES Become the Chip Education Show?

Tuesday, January 12th, 2016

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.


Revisiting System / Scenario / Use-Case Coverage

Wednesday, January 6th, 2016

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
