HSN for Hardware/Software/Network co-simulation

The design and verification of embedded systems requires the integrated simulation of different components belonging to different simulation domains (i.e., software, hardware, network and dynamic systems);
this fact leads to the concept of Hardware/Software/Network co-simulation which is the focus of our tool named HSN.

Concerning SW simulation, HSN uses two Instruction-Set Simulators, the well-known QEMU and uCSim for the wireless sensor network CC2430 platform by Texas Instruments.

Concerning the simulation of HW components, HSN uses SystemC a standard language and simulation environment that reproduces the behavior of concurrent HW and SW systems.

Concerning the simulation of the Network, HSN uses the SystemC Network Simulation Library (SCNSL) (http://scnsl.sourceforge.net/projects/scnsl/) which is an open source library aimed at extending the SystemC simulation capabilities to network components such as packets, links and wireless channels.

Concerning the simulation of dynamic systems, HSN is tightly integrated with MATLAB/Simulink, a well-known environment for designing control, supervisory, and mode logic based on the modeling of differential equations, input/output relationships and state evolution.
