Coupling tools for SpaceWire on-board network: Simulation, Configuration and Validation

In on-board spacecraft architectures, data is increasing rapidly and SpaceWire protocol is used to define high data rate networks. SpaceWire networks have emerged in new avionics architectures for the last years and require tools for dimensioning networks, testing and validating them. One of these tools is MOST (Modelling of On-Board Spacecraft Traffic), embedding a SpaceWire block among several protocols for simulating a traffic over a network. Another one is SPACEMAN which is a discovery and configuration tool. This article explains how both tools are coupled, and how they can be used together for validation, testing or discovery.
