Computer simulation, programming, software, technology, research, and more (since 2007)
In my third post based on the Simics RISC-V simple virtual platform, I use the it to demonstrate how the Intel Simics simulator uses multiple host threads to simulate multiple target cores. The RISC-V platform is nice in that it has less noise than more complex platforms, allowing for clear and simple measurements.
As noted previously, the Public Release of the Intel Simics Simulator has added a simple RISC-V virtual platform.
In my second blog post about the platform, I reconfigure the instruction set, crash Linux, debug the issue, and reconfigure the software to match the hardware.
The 2023-19 version of the Public Release of the Intel Simics Simulator added a simple RISC-V virtual platform. This is the second architecture supported by the public release, after x86.
I will be producing a series of blog posts to show a bit of what the you can do with this virtual platform. The first Intel blog post talks about system-level simulation use cases, in particular networking and simulating x86 and RISC-V systems together.
The 2022 DVCon (Design and Verification) Europe conference was back in physical form at its usual venue at the Holiday Inn München. It was a great conference, and just like at the 2022 DAC people were very happy to be back in person.

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.

The International Conference on Embedded Computer Systems: Architectures, Modeling and Simulation (SAMOS) XXI conference took place a couple of weeks ago. Like all other events in the past 18 months, it was virtual due to Covid-19. For more on the background on the SAMOS conference, see my blog post about SAMOS XIX (from 2019). This year, I presented a tutorial about our public release of the Simics simulator and took the chance to listen to most of the other conference talks.
Continue reading “The SAMOS XXI Conference (Virtual)”I had many interesting conversations at the HiPEAC 2017 conference in Stockholm back in January 2017. One topic that came up several times was the GEM5 research simulator, and some cool tricks implemented in it in order to speed up the execution of computer architecture experiments. Later, I located some research papers explaining the “full speed ahead” technology in more detail. The mix of fast simulation using virtualization and clever tricks with cache warming is worth a blog post.
