Formal Description of Arbitrary Systems by means of Functional Languages

Ziel

The FORFUN project aimed to develop a prototype of a general purpose system description environment based on so-called "system semantics".
System semantics is an extension of the denotational semantics of programming languages in the sense that it is applicable to arbitrary systems, with various properties of a system described by corresponding meaning functions.
A prototype general-purpose system description environment based on functional languages and extended with primitives of system semantics was developed.
Another goal of the project was the design of a prototype system description language for two specific areas: analogue electronic circuits and digital systems (including VLSI).

A prototype general purpose system description environment based on functional languages and extended with primitives of system semantics was developed. Another goal of the project was the design of a prototype system description language for 2 specific areas: analogue electronic circuits and digital systems (including very large scale integration (VLSI)). The feasibility of the approach was demonstrated through case studies using the system description language to describe digital and analog electronic circuits. A general language for system semantics, GLASS, was defined, and a support environment specified. Implementation of the environment is underway through the construction of a coherent set of program generators to support the languages Miranda, Pascal and C. Demonstrations were made in the support of analogue and digital design. Although requiring further development, the basic paradigm shows an important development in the description of systems.

Exploitation
The partners held a seminar to explain the project results to VLSI designers in industry and thus to support their eventual exploitation.
An academic partner is applying the results in analogue circuit design in other projects.
An industrial partner has started the informal transfer of technology to IMEC, the Belgian Inter-University Microelectronics Centre.
