Rapid Partitioning, Automatic Assembly and Multi-Core Simulation of Distributed Vehicle Systems

The advent of heterogeneous specifications of complex systems utilizing both continuous (viz. physics or maths based models) and discrete domain models, communicating via accurate network models, enables a generalization of the usual model-based design methodology. The use of individual notations appropriate for sensor, actuator, plant, controller and accurate network modeling, enable both the natural specification of various models and the continued usage of legacy libraries containing models described in these various notations. The ability to choose fixed or variable-step solvers individually for the simulation of each continuous domain model in a system, enables designers to choose levels of accuracy of models, appropriate network communication models, and speeds of simulation. In this paper, we describe how engineers can rapidly define the connection of hierarchies of modules contained in Simulink models, and their topography distributed across multi-core computers, for fast and accurate simulation.
