Test Automation Meets Simulation

By Paul Henderson

I'm seeing increasing interest from many companies in using simulation environments with test automation systems to accelerate the testing process. Specifically, putting Wind River Test Management together with Wind River Simics is getting creative juices flowing in industry thought leaders.

Why? Well, development teams have started to realize the benefits of simulation systems for speeding and validating system and software design, and for accelerating software development and debug in advance of hardware availabilty. And even when hardware is available, systems like Simics provide tremendous access and control to speed analysis and diagnsotics.

“Good” Android

By Chris Buerger

Following a recent trip to China, I acquired an Android tablet running Release 1.6 (Donut). Total retail price: $90. Unlike an iPad, it is both 'Designed and Made in China.' Running on an ARM platform and containing an 802.11 interface, SD card slot and a touch screen, it is actually a reasonably speedy experience. However, that is where the positive news ends.

Transporting Bugs with Checkpoints

By Jakob Engblom

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.

Consolidate, Consolidate, Consolidate

By Mark Hermeling

Many telecom applications are actually built up from multiple smaller sub-applications, often running on their own server in a rack, ATCA or otherwise. These servers run on multi-core processors, depending on the age of the last refresh this could be a dual, quad core or more. This is of course nothing new, what's new is how virtualization can improve server utilization.

Updates to our VxWorks MILS platform, including a new High Assurance Network Stack

By Bill Graham

This week we announced the latest update to our VxWorks MILS Platform, (for Multiple Independent Levels of Security) which includes a new High Assurance Network Stack (HANS) and guest OS support for Wind River Linux. In a previous post I discussed the growing importance of security in embedded systems. However, in so-called high assurance environments used by military and government organizations, security is an absolute requirement.

Interview with Girish Venkatasubramanian

By Jakob Engblom

After my blog post on Academic Simics earlier this Summer, I got a very nice reply from Girish Venkatasubramanian of UFL. Turned out that he and his group was doing some really interesting and exciting stuff with Simics, researching into Hypervisor architectures and hardware support. Having been a PhD student myself, I can certainly appreciate the excitement and fun of working in that field. We ended up doing a virtual interview, which I am happy to present here.

Wind River and IBM Attack Software Quality

By Paul Henderson

As I've mentioned before, we've been working with IBM Rational for some time around quality management automation. Both companies see the skyrocketing software content and architectural complexity in the embedded device market as creating a tipping point where companies will not be able to continue with business as usual.

Product development teams will need to take a more managed and automated approach to quality that spans across the lifecycle and access into the devices under test. This is particularly true in markets that require strict adherance to standards and compliance regulations.

We put together a joint whitepaper on this subject downloadable from here. And we are also having a joint web seminar next week on Tuesday Aug 31 at 2pm EDT. You can register for this event here.

Type 1 versus Type 2 Hypervisors

By Mark Hermeling

I have always found the difference between Type 1 vs Type 2 hypervisors rather uninteresting. In short, a type-1 hypervisor is a hypervisor that has direct access to the hardware, where a type-2 hypervisor executes inside an operating system. Most hypervisors are type-1 hypervisors, including IT hypervisors such as VMWare, Xen, KVM and such. Type-2 hypervisors are applications like VMWare Workstation (or Fusion), Parallels, .... The distinction between type-1 versus type-2 is really not as useful as most people think. There is a good blog article by Anthony Liguori that describes this as well, complete with references, the article is a bit old, but still correct.

Coming Next Week: Wind River Developer Community for Linux!

By Kay Stanley

We have been busy creating a new resource for our Linux users to connect with others! One of the most high profile and exciting initiatives that I've been tasked with, is to partner with other Wind River staff, and create a place for Linux users of all kinds to come together. We've heard what our customers have been asking for and they were the key drivers behind this project:
