“Pre-Silicon and Post-Silicon Virtual Platforms” – Computer and System Architecture Unraveled Event Six

After a rather long break, we finally had another Computer and System Architecture Unraveled meetup. This time, we had two speakers talking about virtual platforms. Fredrik Larsson from the Simics team at Intel addressed pre-silicon use cases, and Jakob Engblom from the VLAB Works team at Cadence (i.e., myself) talked about uses in Automotive and embedded (mostly post-silicon).

DAC 2025 – All About AI

The 62nd Design Automation Conference (DAC 62) took place in San Francisco, California, USA, from June 22 to 25, 2025. It was the first time in three years that I attended the DAC (this blog is a little bit late, sorry for that). For those that do not know, the DAC is the biggest show in EDA, combining a major research conference with an industry exhibition and engineering track. This year the theme was AI (Artificial Intelligence), and not much else.

What I Saw at the Embedded World 2025

Last week, I visited the Embedded World (2025). Only the exhibition, not the conference part. It was great to be back again, meeting old friends and making new acquaintances in the embedded business. I already told you the dramatic story of how I got there. This blog is about what I saw at the show – trends and technologies.

A Lucky Trip to the Embedded World (2025)

Last week, I visited the Embedded World (2025). Only the exhibition, not the conference part. It was great to be back again, meeting old friends and making new acquaintances in the embedded business. It turns out I was rather lucky in getting there at all – there was that now infamous strike.

“Unusual Perspectives on AI” – Computer and System Architecture Unraveled Event Five

The fifth CaSA, Computer and System Architecture Unraveled, meetup took place on January 30. We finally gave in and joined the AI hype train, resulting in an event with a somewhat different audience and different discussions. More society and applications, less computer architecture. Our two presenters were Håkan Zeffer from SambaNova Systems and Björn Forsberg from RI.SE (doing his second CaSA presentation!). Håkan talked about the architecture of the Sambanova AI processors, and Björn about AI compilers.

“Processor Performance Insights and Optimization” – Computer and System Architecture Unraveled Event Four

Finally, the fourth CaSA, Computer and System Architecture Unraveled, meetup happened on November 6. It took far too long to get it organized, but we finally did it. The theme was about processor performance analysis and efficient processor implementation, offering two talks from very different perspectives. The location was almost the same as before, on the 19^th floor of the Kista Science Tower building. Once more thanks to the sponsorship from Vasakronan and Kista Science City.

DVCon Europe Report on Semiwiki

I posted my first post on Semiwiki! It is a short summary of what we learned at DVCon Europe 2024. Semiwiki is a blog and wiki for the “semiconductor” industry – i.e., it covers topics like EDA tools, semiconductor manufacturing and fabs, hardware design, software design, testing, validation, etc.

DVCon Europe 2024 – AI and More

The 2024 DVCon (Design and Verification) Europe conference took place on October 15 and 16, in its traditional location at the Holiday Inn Munich City Centre. This year there was even more talk of artificial intelligence than last year, and quite a few sessions related to virtual platforms. And lots of other interesting presentations and discussions.

Schloss Dagstuhl (and a Seminar and Cerebras)

A month ago, I participated in a seminar at Schloss Dagstuhl in Germany, about “Discrete Algorithms on Modern and Emerging Compute Infrastructure”. Not my usual cup of tea, but it was very interesting and insightful nevertheless. I have attended a Dagstuhl seminar once before, back in 2003.

Embedded Conference Scandinavia 2024

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.

“RISC-V in Practice” – Computer and System Architecture Unraveled Event Three

On Wednesday, March 13, we had our third CaSA, Computer and System Architecture Unraveled, meetup. Same place as the previous, the 25^th floor of the Kista Science Tower building, thanks to the kind sponsorship of Vasakronan and our collaboration with Kista Science City. The theme this time was “The RISC-V ISA in Practice”, with two speakers named Björn. Another great event!

DVCon Europe 2023 – 10th Anniversary Edition

The 2023 DVCon (Design and Verification) Europe conference took place on November 14 and 15, in the traditional location of the Holiday Inn Munich City Center. This was the 10^th time the conference took place, serving as an excuse for a great anniversary dinner. Also new was the addition of a research track to provide academics publishing at the conference with the academic credit their work deserves. This year had a large number of papers related to virtual platforms, so writing this report has taken me longer than usual. There was just so much to cover.

“Packet Networks are not Socket Science” – Computer and System Architecture Unraveled Event Two

On Wednesday, November 22, we had our second CaSA, Computer and System Architecture Unraveled, meetup. Same place in Kista as the last time, the 25^th floor of the Kista Science Tower building, thanks to the kind sponsorship of Vasakronan and our collaboration with Kista Science City. This time, the theme was networking – but not at the socket level. Per Holmberg presented how his team used “micro sleep” for power management in line-rate network processing, and Hans Brandberg talked about the Precision Time Protocol. Another great event!

IBM WatsonX-AI, Kista Tech Tuesday

I attended a short Tech Tuesday morning session at IBM here in Kista, Sweden, where IBM presented their WatsonX-AI and related technologies. Tech Tuesdays is a monthly technical event organized by Kista Science City, where companies in Kista present some aspect of their technology in a 30-minute session. IBM managed to get an impressive amount of content into that time!

RI.SE AI Day – More on LLMs (and some)

The Swedish research institute RI.SE hosted an “Artificial Intelligence and Computer Science day” (AI and CS day) last week. RI.SE has a long tradition of hosting interesting open houses, both as RI.SE and in their previous guide as SiCS. The day was a mix of organized talks in the morning, and an open house where RI.SE researchers showed off their work in the afternoon. Most of the AI discussions were related to large language models (LLMs), but not all. I got some new insights about LLMs in general and using LLMs for coding in particular.
