open-source – Observations from Uppsala

ChatGPT and Legal

In previous three blog posts (1,2,3) about ChatGPT in particular and large language models in general, I touched on what they can do, what they cannot do, what they seem not to do, how they fall down in funny ways, and why I think they are fundamentally flawed for many applications. There is one more aspect left to consider – the legal and licensing side. I am not a lawyer, I am not an expert, but it seems obvious that there is a huge problem. There are also clear questions about business morals and what the right thing to do would be. I also doubt the business viability of LLMs in the way they are currently trained.

Intel Blog: Open-Sourcing the Device Modeling Language

The Device Modeling Language (DML) that we have used with Simics since 2005 is now available in open source! Some more details and examples of what DML looks like can be found in an Intel blog post.

DAC 2022 – Back in Person, Chiplets, an Award, and Much More

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.

DVCon Europe 2021 – Testbenches, AI, and Open Source

Just like in 2020, the Design and Verification Conference (DVCon) Europe 2021 was a virtual conference. It took place from October 26 to 27, with the SystemC Evolution day on October 28 (as usual). As has been the case in recent years, the verification side of the conference is significantly larger than the design side. This is common with the other DVCon conferences in the world. In this blog, I will go through my main observations from DVCon Europe, and share some notes from some of the presentations.

FLOSS Weekly: Drizzle: Aggressive Push to Multicore

I listened to episode 35 of FLOSS Weekly that interviewed Brian Aker, creator of the Drizzle fork from MySQL. As most recent episodes of FLOSS Weekly, it is pretty good technical material. What I found interesting was the technical vision behind Drizzle, and how they are aggressively going for quite wide multicore hosts.
