Hierarchical Simulation of Onboard Networks

The paper presents a solution for hierarchical simulation of onboard networks, which allows performing simulation at different levels of details. This solution was integrated into a new CAD system - SpaceWire Automated Network Design and Simulation. The paper describes hierarchical simulation component SANDS based on SystemC and methods that it is based on. The overview is followed by methods of SystemC parallelism. Finally, the authors present results of simulation parallelisation and performance testing on a supercomputer.
