Simics for Networked Systems: An Interview with Dan Poirot

Networked systems is one of the primary application areas for Simics. Simics can run many machines inside a single Simics simulation, and apply all Simics features to the system, not just to a single machine inside the system. This is something that Dan Poirot from Real-Time Innovations, RTI, has made quite extensive use of recently. It is a pretty cool use-case for Simics, so we arranged to interview Dan about his use of Simics.

 

The Virtual Basil Fawlty

In the 1970's BBC comedy show Fawlty Towers, John Cleese manages to turn harmless everyday situations into total disasters, with very little effort. It is a marvellous example of how to inject faults into what could have been a smoothly operating hotel, and demonstrating just how things fall apart as the unexpected happens. Injecting faults isn't always that easy, unfortunately (or should that be fortunately)?

Transporting Bugs with Checkpoints

I have a paper about "Transporting Bugs with Checkpoints" to be presented at the S4D (System, Software, SoC and Silicon Debug) conference in Southampton, UK, on September 15 and 16, 2010. The core concept presented is to leverage Wind River Simics checkpointing to capture and move a bug from the bug reporter to the responsible developer. It is a fairly simple idea, but getting it to work efficiently does require that some things are done right.
