Wind River Blog: Stop, Think, and Tie Your Shoes Right

There is a new post at my Wind River blog, which could seem to be about shoes but which is really about process improvement. In particular, the need for companies to let their employees take a step or two back and look at what they are doing and what they could do better.

It is way too common to be so busy running around being inefficient that there is no time to think about how to become more efficient. Change also requires some discipline to actually keep pushing at habits until they change for the better.

All of this can be illustrated by tying shoes.

Wind River Blog: How to Get Virtual

There is a new post at my Wind River blog, about how you build virtual platforms with Simics. The post is more about the methodology than the nature of models, cycle accuracy, endianness, and all the other details of virtual platform modeling. I have written about modeling methodology on this blog too, and in particular I would recommend looking at “Two perspectives on modeling“.

Wind River Blog: Software at the Toddler Stage

There is a new post at my Wind River blog, about the “Toddler stage” of software in general and Simics 4.6 in particular. To me, software in an early stage of development shares many traits with a toddler:

The software will sometimes behave as expected, but more often than not it will not. It will do something else, or crash, or generally do the wrong thing.  It is very much like a toddler – you can rely on it to some extent, but you never know when it will decide to do something unexpected, funny, or just throw a fit over something that would have seemed inconsequential.

 

Wind River Blog: VxWorks 64-bit using Simics

There is a new post at my Wind River blog, about how Simics was used to kick-start the development of the 64-bit version of VxWorks. It is an interesting example of how to use a virtual platform as a model of something much simpler and gentler than actual hardware systems.

Wind River Blog: Testing Integrated Software in Simulation

There is a new post at my Wind River blog, about the testing on an integrated software stack in simulation. I base the discussion on the very interesting report about the Toyota “unintended acceleration” problems and the deep investigation into the control software of the affected vehicles performed by a NASA team (!). The report covers a lot of different tools, but also notes that about the only thing not done was to integrate the complete software stack in simulation.

Wind River Blog: Working Smarter, not Harder

There is a new post at my Wind River blog, about how you can use a virtual platform to complete work faster. Not by making the virtual platform execution of target code faster, but by optimizing the way you work and taking advantage of the features of a virtual platform.

Wind River Blog: Being Helpful or Being Correct?

There is a new post at my Wind River blog, about warnings in virtual platforms. It is an art to add good warnings to virtual platform models, and just being correct visavi the hardware behavior is not necessarily that helpful for a software developer. A virtual platform should warn about suspicious operations, even if they … Continue reading “Wind River Blog: Being Helpful or Being Correct?”

There is a new post at my Wind River blog, about warnings in virtual platforms. It is an art to add good warnings to virtual platform models, and just being correct visavi the hardware behavior is not necessarily that helpful for a software developer. A virtual platform should warn about suspicious operations, even if they are technically “correct”.

I also have to apologize for the slow blogging in January of 2011. There was too much going on at work and quite a few days taking care of sick kids. Hopefully, the pace can improve going forward.

Wind River Blog: Iterative Hardware-Software Interface Design

There is a new post at my Wind River blog, about iterative hardware-software interface design. It is a discussion with some examples of why hardware designers would do well to use virtual platforms to include software designers in the loop when designing new devices and their programming interfaces.

Wind River Blog: “IMA on Simics”

I have a fairly lengthy new blog post at my Wind River blog. This time, I interview Tennessee Carmel-Veilleux, a Canadian MSc student who have done some very smart things with Simics. His research is in IMA, Integrated Modular Avionics, and how to make that work on multicore.
