Nordiske virksomheder modellerer på systemniveau

Det EU-støttede projekt, SYSMODEL, tilbyder nu tilgang til open source systemlevel modellerings-værktøjer. Seks nordiske virksomheder har allerede gennemført projekter (in english).

In order to support the competitiveness of small and medium‐sized enterprises (SMEs) six SMEs from the Nordic countries have teamed up with three recognized R&D providers in the ARTEMIS SYSMODEL project to develop system level modeling tools that can increase their design productivity.

Industry is facing a crisis in the design of complex hardware/software systems. Due to the increasing complexity, the gap between the generation of a product idea and the realization of a working system is expanding rapidly. To manage complexity and to shorten design cycles, industry is forced to look at system level languages towards specification and design.


The SYSMODEL project provides the SMEs with system level modeling tools for the design and implementation of time and power critical, heterogeneous systems. The tools allow the SMEs to build cost‐efficient ambient intelligence systems with optimal performance, high confidence, reduced time to market and faster deployment. The focus is on the development of modeling concepts, methods and tools that master system’s complexity by allowing cost‐efficient mapping of applications and product variants onto an embedded platform; while respecting constraints in terms of resources (time, energy, memory, etc.), safety, security and quality of service.

The general availability of the modeling methodologies is facilitated by the Open Source approach, where all tools are made available free of charge. In order to disseminate the modelling methodologies and tools to a wider group of SMEs the project has established a wiki based entry to tools, models, libraries and tutorials guiding new users through modelling exercises.
The modeling is carried out by describing a system level design in the System Functionality Framework (SFF) and then refining it using the Platform Architecture Framework (PAF).

The project specifies the main concepts of the SFF modeling framework together with the supported models of computation and design languages. Also the basic concepts of the PAF, which is mainly a library of components, are presented. The approach is based on the concept of refinement by replacement, which allows a stepwise refinement of an abstract SFF system model by replacing individual SFF models by executable platform models.

The project will provide four Models of Computation (MoC). Currently the Synchronous MoC, the Discrete Event MoC and the Synchronous Data Flow MoC are implemented. Later also methods and tools for the analysis of embedded applications, developed in the SYSMODEL project will be provided. The success of such new design methods depends on the available analysis techniques, which can quickly evaluate a design alternative from the point of view of performance, predictability, energy, reliability and flexibility. We have concentrated on the development of a SystemC implementation for each MoC‐domain. Other languages (C, VHDL, Matlab/Simulink) will be integrated into the system model using SystemC wrappers.
