Creating Virtual Platform Models
One of the most common questions asked about virtual platforms is: Who creates the models? There are many sources of models and there are people who can make additional models (like Cadence), but obtaining some experience in model creation and virtual platform construction is a great skill to have if you are a software engineer, a hardware ...

Embedded World 2013: Virtual Platforms Connected to Everything
Sometimes it is hard to explain why certain ideas take off and why others don’t. There are many stories of poor products that are more successful than much better products. There are also many stories about products that struggle in one time or place, but the same thing is a big hit at another time in history. This is especially ...

A Concrete Linux Virtual Platform Example
Virtual platforms are used to find many different types of system and software issues. Of course, platforms take some time to develop and debug (regardless of what you read in marketing brochures), but in most situations the benefits outweigh the time and effort required for platform creation. Generally, I think of platform creation as a ...

Update to the Linux Kernel Message System
A few months ago I wrote an Introduction to the Linux Kernel Message System. As with all software, especially Linux, things get out of date and need updating. The Linux 3.5 kernel contained changes to the kernel message system that are relevant to my previous article. I found coverage of the changes at LWN.net posted in April and May. The new ...

Creating Custom File Systems and the Linux Loop Device
A few weeks ago we had a crisis at our house. My son managed to delete the data from my daughter's USB memory stick. Not only did he delete it, but he did it in such a strange way I have no idea what he could have done. She was not too happy since all of her recent school work was on the memory stick. My best guess is that he deleted it ...

Using a Network File System with the Xilinx Zynq-7000 Virtual Platform
There are a number of ways to do embedded software development for Xilinx Zynq-7000 based designs. For embedded Linux projects, Zynq offers multiple storage options such as SD card and USB. It's also possible to use a ramdisk for the root file system during development. Today, I will cover how to use the Network File System ...

I was ...

Improving SimVision Fonts for Ubuntu
This article is a follow-up on an early 2012 article about using Incisive and Virtual System Platform on the Ubuntu operating system. Although the feedback has been positive, the one area that was not covered very well is the look of SimVision. When I wrote the original article I used Ubuntu 11.10, and the fonts in SimVision seemed to get worse ...

Previously, I posted two articles involving Henry including an interview and a HOWTO about verification and virtual platforms. This time Henry covers an often asked topic related to the virtual platform for the Xilinx Zynq-7000 EPP by ...
