Romanowicz, Bart ; Laudon, Matthew ; Lerch, Philippe ; Renaud, Philippe ; Amann, Hans-Peter ; Boegli, Alexis ; Moser, Vincent ; Pellandini, Fausto

In: IEEE Proceedings of European Design and Test Conference (ED&TC), 1997, p. 119-123

The analytical modeling and simulation of conservative electrostatic, electromagnetic and electrodynamic transducers found in microsystems using a non-linear lumped-parameter approach is presented in this paper. A comparison is made between this approach and the linearized equivalent circuit method. All models of transducers are written in HDL-ATM, a proprietary analogue hardware description...

Generating VHDL-A-like Models Using ABSynth

Moser, Vincent ; Nussbaum, Pascal ; Amann, Hans-Peter ; Astier, Luc ; Pellandini, Fausto

In: IEEE Proceedings of European Design Automation Conference (EURO-DAC) with EURO-VHDL, 1995, p. 522-527

A method for the graphical specification and the automatic generation of analogue behavioural models is presented. This method has been implemented as a new software tool called ABSynth. The behaviour of the component to model is described as a functional diagram, which is then automatically translated into a VHDL-A-like analogue hardware description language. No syntax knowledge is necessary and...

A graphical approach to analogue behavioural modelling

Moser, Vincent ; Nussbaum, Pascal ; Amann, Hans-Peter ; Astier, Luc ; Pellandini, Fausto

In: IEEE Proceedings of the European Design and Test Conference (EDTC) ; European Conference on Design Automation (EDAC) ; European Test Conference (ETC) ; European Event in ASIC Design (EUROASIC), 1994, p. 535-539

In order to master the growing complexity of analogue electronic systems, modelling and simulation of analogue hardware at various levels is absolutely necessary. This paper presents an original modelling method based on the graphical description of analogue electronic functional blocks. This method is intended to be automated and integrated into a design framework: specialists create behavioural...

High-level modeling using extended timing diagrams - A formalism for the behavioral specification of digital hardware

Moeschler, Philippe ; Amann, Hans-Peter ; Pellandini, Fausto

In: IEEE Proceedings of the European Design Automation Conference (EURO-DAC), with EURO-VHDL '93, 1993, p. 494-499

The principles of high level modeling of digital hardware circuits using the extended timing diagrams (ETD) formalism, which adds conditions, events, action expressions, and particular constraints to traditional timing diagrams, are described. Hierarchy and concurrency are also integrated so that a full top-down design becomes possible, enhancing at the same time the readability. While, for...

Behavioural Modelling of Analogue Systems with Absynth

Moser, Vincent ; Amann, Hans-Peter ; Pellandini, Fausto

In: Analog and mixed signal description languages, Current Issues in Electronic Modeling, 1997, vol. 10, no. 6, p. 103-130

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...
