The COSSIM simulation framework is the first known open-source, high-performance simulator that can handle holistically system-of-systems including processors, peripherals and networks; such an approach is very appealing to both Cyber-Physical Systems (CPS) and Highly Parallel Systems (HPS) designers and application developers.

COSSIM is built on top of several well-established simulators:

• GEM5, a state of the art full-system simulator, to simulate the digital components of each processing node in the simulated system.
• OMNeT++, which is an established network simulator, to simulate the networking infrastructure.
• McPAT to provide energy and power consumption estimations of the processing nodes and MiXiM (OMNeT++ addon) to estimate the energy consumption of the network.

To bind the whole framework together, COSSIM employs the HLA architecture through the open-source CERTI package. Additionally, a sophisticated Eclipse-based GUI has been developed to provide easy simulation set-up, execution and visualization of results.
