A Bus Level SystemC Model for Evaluation of Avionics Mission System Data Bus

This paper presents a bus level SystemC model of an avionics mission system data bus. The mission system is a very complex distributed computer network consisting of mission control computer, radars, an array of subsystems and sensors. The data bus plays a central role in the system as it carries all the information between the system components. Therefore modeling the bus at an appropriate level of abstraction using appropriate technology is very important for evaluation of the performance of both the bus and the entire system. We explore the benefits of using SystemC in modeling such a critical data bus. The developed model has been validated for various payloads and system size. The enhanced features of SystemC makes the model more efficient in some respect compared to models developed using conventional hardware description languages.
