They synchronize through events and exchange data.

Functional architecture describes applicative structures with timed behaviors.

The result is a refined virtual system model. The application model is mapped onto the platform model to add generic physical constraints. The application or functional model includes elements of the environment-generating stimuli for system simulation under specific scenarios or use cases. The model packaging reflects the separation between the application and platform models. The generic platform consists of a processor and a hardware accelerator.

It is a high-level description of an audio-video decoder running on a generic platform. It does, however, offer an optional profile to represent several features related to CoFluent DSL and necessary for efficient embedded system modeling and simulation.Īn example of a model for a multimedia application is used to illustrate the design flow. The CoFluent methodology for UML does not add new elements to standard profiles. These rules enable the simulation of multicore/multiprocessor hardware/software (HW/SW) system models for behavioral and performance data prediction without restricting the expressiveness of SysML and MARTE. The methodology can be described as a set of modeling rules and restrictions applied to SysML/MARTE. It allows automatic model transformation from this format to the CoFluent domain-specific language (DSL). The methodology is based on UML with the Systems Modeling Language (SysML) and the Modeling and Analysis for Real-Time and Embedded Systems (MARTE) profiles. This paper presents the CoFluent Design methodology for the Unified Modeling Language (UML) and associated tool support. The CoFluent methodology delivers modeling rules and methods with tool support.

The methodology offers simulation of multicore/multiprocessor hardware/software embedded system and chip models, enabling designers to observe system behavior and analyze performance properties. CoFluent Design has therefore developed a methodology for UML to provide a comprehensive framework and guidelines for the joint use of UML, SysML and MARTE.

Unfortunately, it remains mainly descriptive in nature, because no commercial tools are available to simulate the models and extract performance data. The Modeling and Analysis for Real-Time and Embedded Systems (MARTE) UML profile attempts to fill this gap by providing elements from both embedded software and hardware engineering. However, this profile is too generic to address embedded and real-time system design. System Modeling Language (SysML) is a Unified Modeling Language (UML) profile that allows the creation of standard descriptions of a system.
