Virtually broken
Editor's Note
Beginning as far back as the year 2000 in "Taking system design to a higher level," Embedded.com has maintained an on-going interest in the use of virtual prototyping platforms to simplify the integration of the hardware and software of embedded systems designs. Then it was a methodology only used in extreme cases when chip integration densities were still moving in on one micron geometries. Now, as system-on chip designs are closing in on 10 nanometers, virtual system prototyping of hardware and software has become a necessity in many embedded designs.
Illustrating the power virtual prototyping is a three-part series concluding this week on Embedded.com: Part 1 "ARM-based Android hardware-software design using virtual prototypes," in which Achim Nohl describes how to use the Synopsys Virtualizer Development Kit (VDK) to do early prototyping. He also explains how to do full software integration of handset hardware in the context of the Android software platform. In Part 2, Nohl describes "Building a sensor subsystem." Part 3 on integrating Android's HAL will be available later this week. Of the many recent design articles, technical papers and webinars included here that delve even deeper into the use of virtual system prototyping, my Editor's Top Picks are:
How to make virtual prototyping better than designing with hardware
Exploring Multicore Power Management with Modeling and Simulation
Leveraging virtual hardware platforms for embedded software validation
For additional insight, be sure to read some of the recent technical journal and conference papers on such topics as the use of virtual prototyping of mobile devices, embedded signal processing systems, and multicore system performance analysis.
