Object-oriented modeling and Co-simulation of embedded systems

摘要

This paper presents the modeling and co-simulation capabilities of S~3E~2S, a design environment for electronic systems that can be built as a combination of analog and digitalparts and software. S~3E~2S is based on a distributed, object-oriented system model, where abstract objects are initially used to express complex behavior and may be later refined into digital or analog hardware and software. Co-simulation of any heterogeneous model developed during a stepwise refinement process is supported. These capabilities are illustrated by the modeling of a crane and its embedded control.
