    Summary
    In this paper, we present the computer-aided analogue behavioural modelling tool ABSynth (Analogue Behavioural model Synthesizer). The behaviour to model is expressed graphically in the form of a Functional Diagram (FD) drawn as the interconnection of Graphical Building Symbols (GBS), each of which stands for some elementary analogue behaviour. The functional diagram describes the behaviour of the system only, not its physical structure. The corresponding HDL-A™ code is then generated automatically.

    The novel contribution of this work is threefold : first, analogue behaviour can be described in a dedicated graphical form, secondly, the graphical description is translated into behavioural AHDL code, lastly, the graphical description method and the code generation process have been implemented as a software tool. This tool, ABSynth, is user-friendly, easy to extend, and integrated in a complete design environment. The generated code is syntactically right by construction and, consequently, the user does not need to know the syntax of the target hardware description language anymore.
