Simulation of Virtual Circuits

Model-Based Design with Real-Time-Capable SystemC/SystemC AMS Models on dSPACE hardware
February 27, 2012: In the development process of integrated electronic components, creating models and testing the system behavior virtually, meaning with a simulation-based method, is the state-of-the-art procedure. To create executable specifications, design the system architecture and develop the embedded software at an early stage, more and more developers are turning to the description language SystemC/SystemC AMS, based on the programming language C++. Many suppliers of integrated components are already offering models in this description language and using them in their development process.
The language's excellent number of abstraction levels make it possible to design quickly executable simulation models with enough accuracy and with a fitting level of detail. These models can be optimized to such a high degree that they can be calculated in real time. Porting SystemC/SystemC AMS onto dSPACE hardware and synchronizing the simulation time axis with real time was therefore a natural choice. With this porting, performed by the Fraunhofer Institute IIS/EAS in Dresden, it is now possible to apply abstract hardware and software models, including the analog components from the circuit design process, onto dSPACE systems for rapid control prototyping (RCP) and hardware-in-the-loop (HIL) simulation. Thus, developers are now able to test the specification of circuit's hardware components in real systems long before they exist physically.
The Fraunhofer Institute for Integrated Circuits IIS (Design Automation Division EAS) will be showing an experimental demo system at the "embedded world 2012" exhibition from February 28 to March 1, 2012 in Nuremberg (Hall 4, booth 4-128).
