Object-Oriented Modeling and Co-Simulation of Embedded Systems

This paper presents the modeling and co-simulation capabilities of S3E2S, a design environment for electronic systems that can be built as a combination of analog and digital parts and software. S3E2S 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.
