Project Objectives

The high-level objective of the ODETTE project is to support the competitiveness of the European communication and information processing industry by reducing the entire design time and cost of digital embedded HW/SW systems. The prime deliverable of the ODETTE project is a system for object-oriented HW/SW co-design, which provides a migration path from object-oriented system specifications to efficient HW and SW implementations. This method differs from existing co-design methodologies in its seamless synthesis and optimisation of the HW design directly from object-oriented specifications, and its generation of the SW code. Through object-orientated synthesis, it is possible to develop an early prototype, where the object-orientation characteristics support reuse of SW and HW components.

ODETTE will aim at avoiding the paradigmatic breaks between system specification, SW development and HW design. By applying a holistic, consistent, and automated design methodology to the entire system on a chip design and functional design verification, an efficient design exploration and optimisation process will be enabled. In other words, the same analysis, modelling, and structuring paradigms will be used for the entire system, regardless of whether the implementation will be made in software or hardware.

In order to achieve this objective in a sustainable way, the following sub-goals will be pursued in the project:

  • Build and demonstrate a complete working design flow from system specification to the logic synthesis level, with significant gains in design time and efficiency, and with minimal overhead in terms of area.

  • Support design and architecture reuse, through a consistent object-oriented design methodology supported by appropriate encapsulation and derivation mechanisms of the design modelling languages.

  • Interface to industry standard design flows.

  • Implement the design methodology in an efficient tool set, where not available commercially.

  • Provide a tool package for further dissemination and external exploitation.

  • Evaluate and quantify the results of the project.

  • Develop and market a complete co-design solution including HW/SW co-simulation and synthesis tools, using as input object-oriented description languages for both HW and SW designs.

  • Augment the European CAD product offerings with innovative software in the rapidly increasing market of co-design tools.

These objectives can be achieved by joining forces and competence on a European level.

Description

The workplan is structured into four technical workpackages, one on dissemination and exploitation, and one administrative workpackage. The consortium has been formed to bring together the necessary expertise and business interest for this challenge. It consists of a European telecommunication system house (Siemens ICN S.p.A., Milano, Italy), an International system house (IBM Science and Technology Ltd. Haifa, Israel), a European CAD vendor (Synopsys LEDA, Saint Martin d'Heres, France), a European research institute (OFFIS, Oldenburg, Germany), and a European CAD standardisation institute (ECSI, Gieres, France). The project co-ordination is done by OFFIS.

Workpackage 1 covers the detailed methodology definition and preparation of methodological guidelines usable by designers as well as the creation of reuse libraries coherent with the methodology. The technical workpackages 2 and 3 are structured according to the anticipated tool packaging of the project and the intended specification - implementation - evaluation cycle of the tool and methodology implementation. The partners will develop tools to process C++ and Objective VHDL code that complies with the object-oriented methodology based on class, inheritance, object instantiation, object communication and polymorphism. The tools will allow to verify the system description by simulation of functional tests, and to synthesise it to software and hardware. While Workpackage 2 implements the co-simulation tool, Workpackage 3 deals with hardware synthesis from object-oriented descriptions in C++ and Objective VHDL. In fact both workpackages are closely linked by the common definition and usage of the intermediate format. Workpackage 4 will evaluate the design methodology and the tool set by industrial applications. The exploitation of the results (Workpackage 5) will be twofold: Internally by all industrial partners and the research institute by applying the methodology, libraries and tools for future product developments as well as by an exploitation of the test cases, and secondly by external exploitation of the tool set.
