Computer simulation, programming, software, technology, research, and more (since 2007)
In my previous blog about the Ghostwrite vulnerability in the Alibaba T-Head C910 RISC-V-based processor, I noted that the authors of the paper had found more than just that one bug. The additional bugs are worth their own write-up, as they offer some more examples of what looks to be poor testing.

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.
