Making Sense Of Virtualization
By Achim Nohl - 22 Mar, 2012 - Comments: 0

By Achim Nohl In the last month I’ve had the opportunity to get some hands-on experience with hardware virtualization and hypervisors. My knowledge so far on this has been mainly limited to what I could read about it and what other people are saying about it. However, the PowerPoint slides I’ve seen leave a lot of white fog between the bullet items. This didn’t make me feel very comfo... » read more

What Have Models Got To Do With It?
By Achim Nohl - 23 Feb, 2012 - Comments: 0

By Achim Nohl Transaction-level models are the main building blocks of virtual prototypes, which are used for early software development. In my last blog post, I briefly introduced the different kinds of software tasks and the implications for models. Today, I want to talk about the modeling requirements for early SoC bring up. As I mentioned, understanding the software requirements correct... » read more

Model Behavior
By Achim Nohl - 26 Jan, 2012 - Comments: 0

By Achim Nohl In this post, I would like to share some perspectives on the transaction-level models needed for the creation of virtual prototypes. Just recently, TLMCentral kicked off a contest seeking the “best” model for a mobile phone sensor device. What actually makes a “good” model? The most ad-hoc answer to this question historically has been that the best model is the fastest an... » read more

Increase The Battery Mileage With Virtual Prototypes
By Achim Nohl - 15 Dec, 2011 - Comments: 0

By Achim Nohl With this post, I would like to continue the topic of my earlier post “Can we stop power-hungry bugs from clawing their way through application software stacks?” In my previous post, I wrote about the difficulties software developers face with writing battery-friendly software. I indicated that virtual prototypes (VPs) can address many of those challenges by providing visibil... » read more

Pest Control

By Achim Nohl Identifying and describing power issues is tough, let alone trying to solve them. “Power” issues can be very diverse. It’s even more difficult to explain how virtual prototypes can help to analyze “power” consumption. We often approach it by introducing how power information can be reflected in virtual prototype models, but there are many different goals and conflicting... » read more

Early Software Development And The Supply Chain
By Achim Nohl - 20 Oct, 2011 - Comments: 0

By Achim Nohl In my last blogs I have been focusing on introducing the technical advantages of virtual prototypes in the context of debugging embedded software. In this blog I would like to introduce how this can impact an entire supply chain. The increasing complexity of software in terms of code-size, functions and layers, along with multicore SoCs, also demands more capable debug solutio... » read more

VP Software Debugging: Myths And Facts
By Achim Nohl - 22 Sep, 2011 - Comments: 0

By Achim Nohl In my last post I introduced the debugging challenges during porting, or developing native code, for Android. This time I would like to outline how virtual prototypes can enable software debugging and perform in an even better way. Before I describe what “better” refers to exactly, I want to shed some light on some prominent myths around the value of VPs for debugging. W... » read more
