The Embedded Conference Scandinavia took place at Kistamässan in Kista, Sweden, on April 10 and 11 2024. This was a reboot of a show that used to run as a small tradeshow/exhibition plus technical talks until the pandemic hit. There was no Embedded Show anymore, just the Embedded Conference and its speaker program. The ECS was instead co-located with Elektronikmässan, the long-running and apparently thriving gathering for “electronics” companies in Sweden.

The Mathworks Automotive Conference (MAC) 2022
The Mathworks Automotive Conference (MAC) 2022 was one-day vendor-specific conference about how Mathworks products can be/are used in the automotive sector. The set of companies represented was truly impressive. There were presentations from Lightyear, MAN, Mercedes-Benz, Volvo, Infineon, Toyota, Bosch, Continental, Real-Time Innovations, and of course the Mathworks themselves. It was a day well-spent listening to interesting talks. Here is my personal summary.

The 59th Design Automation Conference (DAC) took place in San Francisco, July 10-14, 2022. As always, the DAC provided a great place to learn about what is going on in EDA. The DAC is really three events in one: there is an industry trade-show/exhibition, a research conference that is considered the premier in EDA, and an engineering track where practitioners present their work in a less formal setting.
I had two talks in the engineering track – one on the Intel device modeling language (which actually won the best presentation award in the embedded sub-track), and one on using simulation technology to build hardware software-first.
The DAC was almost overwhelming in the richness of people and companies, but this blog tries to summarize the most prominent observations.

Back in 2016, the European Space Agency (ESA) lost the Schiaparelli Mars lander during its descent to the surface on Mars. From a software engineering and testing perspective, the story of why the landing failed (see for example the ESA final analysis, Space News, or the BBC) is instructive. It comes down to how software is written and tested to deal with unexpected inputs in unexpected circumstances. I published a blog post about this right after the event and before the final analysis was available. Thankfully, that has since been retired from its original location-it was a bit too full of speculation that turned out to be incorrect… So here is a mostly rewritten version of the post, quoting the final analysis and with new insights.

Wind River is celebrating their 40th anniversary as a company with a series of historical look-backs posted on the Wind River channel on YouTube. One of the videos is an interview with Jerry Fiddler who founded Wind River back in 1981, by Wind River current CEO Kevin Dallas. Jerry Fiddler talks about how he got started in computers, and especially about how Wind River got started and grew. It is both a fantastic set of historical anecdotes and some solid product management and strategy insights.

Back when I was a PhD student working on worst-case execution-time (WCET) analysis, one of the leading groups researching the topic was the “Saarbrücken gang” led by Professor Reinhard Wilhelm. Last year, Professor Wilhelm published a retrospective look on their work on WCET in the Communications of the ACM. It is a really interesting history write-up from the perspective of the Saarbrücken group.

The July 2020 edition of the Communications of the ACM (CACM) had a front-page theme of “Domains-Specific Hardware Accelerators”, or DSAs. It contained two articles about the subject, one about an academic genomics accelerator, and one about the Google TPU. Hardware accelerators dedicated to particular types of computation are basically everywhere today, and an accepted part of the evolution of computers. The CACM articles have some good tidbits and points about how accelerators are designed and used today. At the same time, I also found a youtube talk about the first hardware accelerator, the IBM Stretch HARVEST, showing both contrasts with today as well as a remarkable continuity in concept.

Last week was spent at the Design Automation Conference (DAC) in Las Vegas. I had a presentation and poster in the Designer/IP track about Clouds, Containers, and Virtual Platforms , and worked in the Intel Simulation Solutions booth at the show floor. The DAC was good as always, meeting many old friends in the industry as well as checking out the latest trends in EDA (hint: same trends as everywhere else). One particularly nice surprise was a book (the printed type, not the Vegas “book” that means something else entirely).

The Embedded World in Nürnberg is still going strong as the best tradeshow for “Embedded” in the world. This year, I spent time doing booth duty and gave a talk in the Conference part of the event. There was an unusual high number of old friends and business acquaintances around, and it was a great experience overall with many fruitful discussions and connections for the future. However, it seems that there is always something that goes slightly awry with my travel to the show…

I work with virtual platforms and software simulation technology, and for us most simulation is done on standard servers, PCs, or latptops. Sometimes we connect up an FPGA prototype or emulator box to run some RTL, or maybe a real-world PCIe device, but most of the time a simulator is just another general-purpose computer with no special distinguishing properties. When connecting to the real world, it is simple standard things like Ethernet, serial ports, or USB.
There are other types of simulators in the world however – still based on computers running software, but running it somehow closer to the real world, and with actual physical connections to real hardware beyond basic Ethernet and USB. I saw a couple of nice examples of this at the Embedded World back in February, where full-height racks were basically “simulators”.

Intel Blog Post: Simulation a Thousand Target Machines – in 2004 and 2018
Back in 2004, the startup Virtutech built a crazy demo for the 2004 Embedded Systems Conference (ESC). Back then, ESC was the place to be, and Virtutech was there with a battery of demos to blast the competition. The most interesting demo from a technology perspective was the 1002-machine network, as described in an Intel Developer Zone blog post of mine.

A Little Snow Sure Can’t Hurt?
I had the honor to have a scheduled talk at the Embedded World 2018 show in Nürnberg, right at the start of the show on Tuesday morning. Getting to Nürnberg for the Embedded World without paying a fortune for plane tickets is tricky due to all the other people flying down from Swedish embedded and tech firms at the same time. This year, I was lucky and I had managed to get a very convenient flight at a decent price. Leaving Stockholm in the afternoon around 14.00 on Monday, flying via Frankfurt and then on to Nürnberg, arriving in the early evening just in time for a nice Bavarian dinner. No stress, no late evenings on the U-Bahn into town. A good night’s sleep before getting up and getting to the show with plenty of time to set up for my talk. What could possibly go wrong?
Talking at the Embedded World 2018
I will be presenting an Exhibitor Forum talk at the Embedded World in Nürnberg next week, about how to get to Agile and small batches for embedded. Using simulation to get around the annoying hard aspect of hardware.

Intel Blog Post: Getting to Small Batches in System Development using Simulation
I have posted a two-part blog post to the public Intel Developer Zone blog, about the “Small Batches Principle” and how simulation helps us achieve it for complicated hardware-software systems. I found the idea of the “small batch” a very good way to frame my thinking about what it is that simulation really brings to system development. The key idea I want to get at is this:
[…] the small batches principle: it is better to do work in small batches than big leaps. Small batches permit us to deliver results faster, with higher quality and less stress.

Smart Locks Bricked by Bad Update? The Right Approach!
I read some news (ExtremeTech, Techcrunch) about how “smart” wifi-connected locks sold by Lockstate got bricked by an automatic over-the-network update. This sounds bad – but it is bad for a good reason. I think the company should be lauded for actually having the ability – and laughed out for royally botching it.
