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).Continue reading “DVCon Europe 2020 – Developing Hardware like Software?”

Neat Register Design to Avoid Races
In his most recent Embedded Bridge Newsletter, Gary Stringham describes a solution to a common read-modify-write race-condition hazard on device registers accessed by multiple software units in parallel. Some of the solutions are really neat!
I have seen the “write 1 clears” solution before in real hardware, but I was not aware of the other two variants. The idea of having a “write mask” in one half of a 32-bit word is really clever.
However, this got me thinking about what the fundamental issue here really is.
Conquering Software with Software High-Level Synthesis
This post is a follow-up to the DAC panel discussion we had yesterday on how to conquer hardware-dependent software development. Most of the panel turned into a very useful dialogue on virtual platforms and how they are created, not really discussing how to actually use them for easing low-level software development. We did get to software eventually though, and had another good dialogue with the audience. Thanks to the tough DAC participants who held out to the end of the last panel of the last day!
As is often the case, after the panel has ended, I realized several good and important points that I never got around to making… and of those one struck me as worthy of a blog post in its own right.It is the issue of how high-level synthesis can help software design.
