Intel – Observations from Uppsala

“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).

Working in EDA for Real (Finally)

In late May, the VLAB Works part of ASTC was acquired by Cadence, and as a result I am finally working in EDA for real. What a change! When I started working with the Simics simulator at Virtutech in 2002, we were at pains to distance ourselves from EDA. Now, almost 25 years later, I am working in one of the big three EDA companies.

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.

New Job, New Simulator

As already leaked by LinkedIn, I recently started a new job at ASTC, as Global Technical Marketing Manager for the VLAB virtual platform product. This is my first major change of job I since I joined Virtutech to work on the Simics simulator back in 2002. It is both a big change and a small change – staying in the world of virtual platforms, but working with a new product that is quite different from Simics. In fact, more things are different and new and fresh than the same…

More Exploration of (Local) AI Models

In my previous blog post about the Intel AI Playground, I tested it by asking it to draw cars. In this post, I share some more exploration of these local AI models and their limitations. Turns out that cars are easy, other things not so much…

Hi Local AI, Draw Me …

I recently built a new desktop computer, featuring an Intel ARC 770 graphics card (just to be different). The card is supported by the Intel AI Playground, which is a software package that makes it dead easy to run AI/large language models (LLM) locally on my GPU. I was curious as to just what this could do, as compared to the big AI models that run on cloud servers.

Time to Do Something New

The time has come to do something new. I am leaving Intel (and the Intel Simics team) at the end of September (2024). After more than twenty years with the team and the product this is a big step into the unknown. But when Intel offered a “retirement” package as part of its current round of cost reduction measures, I felt that it was a golden opportunity to find something new to do.

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.

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.

The first Computer and System Architecture Unraveled Event in Kista – Great Speakers, Great Fun!

On the evening of the last Wednesday in September, we had our first CaSA, Computer and System Architecture Unraveled, event. CaSA is a meetup in Kista (Sweden) for people interested in computer architecture, system architecture, and how software and hardware interact down towards the lower levels of the stack. The topic for the inaugural event was “Core Count Explosion: A Challenge for Hardware and Software”, and it was great in some many ways!

The NUC12 Enthusiast

Right when our old NUC5 died, its replacement had been delivered and brought online – a new Intel NUC12 Enthusiast, also known as the NUC12SNKi72 (I work at Intel, but even I find that name a bit obtuse). This is a seriously fast machine in a fairly compact package, even though admittedly not as small as the old NUC5. On the other hand, as a machine with an ambition to be a replacement for a dedicated gaming PC, it sports a dedicated graphics card and not just the integrated graphics typical for the classic NUCs.

This NUC is Dead

Computers can wear out given enough time. I just had an old NUC basically fall apart – on the very day it was being replaced by a new one. The timing is rather too good to be believed, but basically the machine stopped working just when we transitioned to a new NUC. The old one still booted… but running it was questionable due to its many concurrent failure modes.

Two Presentations at DVCON Europe 2022

DVCon (Design and Verification Conference) Europe is coming up in early December, in person, in München, Germany. The selection of papers and posters is finished, and the program is firming up. I am happy to report that I am part of two items on the menu, a personal record for DVCon! For more on DVCon Europe in general and how it has been in the past, see my previous blog post on DVCon Europe 2022.

Intel Blog: Catching a Tricky Bug by Running Simics on Simics

I recently published a long post on the Intel Community Blog, talking about how my colleague Evgeny solved a nicely complicated bug using Simics-on-Simics. The bug involved UEFI, an operating system, SMM, SMI, and virtualization. Just another day in the office (or more like a year, given how long it took to get this one resolved).

DVCon Europe 2020 – Developing Hardware like Software?

The Design and Verification Conference Europe (DVCon Europe) took place back in late October 2020. In a normal year, we would add “in München, Germany” to the end of that sentence. But that is not how things were done in 2020. Instead, it was a virtual conference with world-wide attendance. Here are my notes on what I found the most interesting from the conference (for various reasons, this text did come out with a bit of delay).
