Dataflow/Actor-Oriented language for the design of complex signal processing systems

Marco Mattavelli, Christophe Lucarz, Ghislain Roquier

Signal processing algorithms become more and more complex and the algorithm architecture adaptation and design processes cannot any longer rely only on the intuition of the designers to build efficient systems. Specific tools and methods are needed to cope ...

Modeling embedded systems using SystemC extensions

Alain Vachoux

SystemC AMS extensions introduce new language constructs for the design of embedded analog/mixed-signal systems. This paper presents the novel modeling language for analog and mixed-signal functions that supports design and modeling of telecommunications, ...

Proposal to Extend SystemC-AMS with a Bond Graph Based Model of Computation

Yusuf Leblebici, Alain Vachoux, Torsten Mähne

There is a need to improve the modelling capabilities of SystemC-AMS concerning conservative continuous time systems involving the interaction of several physical domains and the interaction with digital control components. Bond graphs unify the descriptio ...

Improvements for Constraint Solving in the SystemC Verification Library

For verification of complex system-on-chip designs often constraint-based randomization is used. This allows to simulate scenarios that may be difficult to generate manually. For the system description language SystemC the SystemC Verification (SCV) Librar ...

Proposal for a Bond Graph Based Model of Computation in SystemC-AMS

Alain Vachoux, Torsten Mähne

SystemC-AMS currently offers modelling formalisms with specialised solvers mainly focussing on the electrical domain. There is a need to improve its modelling capabilities concerning conservative continuous time systems involving the interaction of several ...

Compact Modeling of MOSFET in VHDL-AMS

Alain Vachoux, Christophe Lallement

In this chapter, we present the capabilities of the VHDL-AMS hardware description language for developing compact models. After a brief description of the VHDL-AMS language, we present two meaningful case studies on design oriented models of MOSFET. The fi ...

Modeling and Simulation of Multi-Discipline Systems using Bond Graphs and VHDL-AMS

Alain Vachoux, Christophe Lallement

Bond graphs represent a convenient tool for physical system analysis. While it is one part of the job to establish a pertinent bond graph model, it is another important part of the job to take advantage of this bond graph. A simulation tool is involved and ...

Towards Analog and Mixed-Signal SOC Design with SystemC-AMS

Alain Vachoux

Systems-on-Chip (SoCs) are heterogeneous by nature as they may integrate digital, analog, RF hardware as well as software components or non electrical parts such as sensors or actuators. The increasing level of complexity for designing SoCs in a reasonable ...
