So what comes after FinFETs? At 14/16nm (or 22nm if you are Intel) we had FinFET transistors, where the channel was no longer planar but stuck out of the wafer vertically, and the gate wrapped around it on 3 sides. The key thing that made FinFET transistors attractive was that the channel was thin so that the gate controlled it well. … Read More

Layout-aware Diagnosis
Traditional test methodologies have been based on the functional model, that is to say the netlist. The most well-known is probably the stuck-at model which grades a sequence of test vectors by whether they would have managed to notice the difference between a fully functional design and one where one of the signals was permanently… Read More
What is the Latest in Mobile?
Most of the results are in for mobile for last quarter, plus the earnings calls are all over. The picture is not pretty. The big picture is that low-cost Android-based suppliers, primarily in Asia, are starting to eat a lot of market share from Samsung (#1) and Apple (#2). There were about 295M smartphones shipped in Q2, a measly 2% … Read More
The Carrington Event
Back in the pre-SemiWiki days when I had the EdaGrafitti blog I wrote about the Carrington event. This was a solar storm in 1859 that lasted for several days. On September 1st there was a coronal mass ejection (CME) traveling directly towards earth. Normally such an event would take several days to reach earth but an earlier ejection… Read More
Open Source Verilog
Over the years there have been various open source EDA projects but none that has realized a full industrial strength design tool that has broad adoption and is strong enough to compete with similar products from the EDA industry.
Open source is clearly a great way to develop software. Lots of people can see all the source code and … Read More
eSilicon and the Ten Minute Quote
One of the challenges in bringing a design into production is getting a quote that includes all the various stages of the process. The quote cycle typically takes a couple of weeks. It is also pretty wasteful. A typical design might be quoted by 3 manufacturers and so 2 out of 3 quotes are wasted expense because the design is lost to a … Read More
EUV Pellicles
Shakespeare reckoned that a man went through seven stages in his life.All the world’s a stage, And all the men and women merely players. They have their exits and their entrances, And one man in his time plays many parts, His acts being seven ages.
Well, an EUV mask seems to only go through three main stages:

Pizza con Questa
Last week I went to a lunch and learn at Mentor about their Questa formal product given by Kurt Takara. Like everyone else these days, Questa is packaged as a number of Apps for doing different tasks. Formal verification is different from other EDA tools in that different approaches can be used for different sub-tasks. There are three… Read More
Realibrium.com: EDA for Real-estate
Everyone in EDA is really smart. People who leave EDA and go and work in other industries, especially people who left in the late 1990s for internet startups, notice that this is not true elsewhere. Not that there aren’t smart people in internet startups, just that not everyone is. EDA is an industry where you need a master’s… Read More
ARM’s Quarterly Results: Licensing Strong, Royalties Weak, Future is Bright
Last week was ARM’s quarterly earnings call. Simon Segars, the CEO, and Tim Score, the CFO, presented from London.
First, the numbers:
- revenue was up 17% year-on-year in dollar terms to $309.6M, but only 9% in Sterling terms due to exchange rate moves to £187.1
- profit before tax was $94.2M
- licensing was up 42% year-on-year
