Virtual Prototyping Methodology for Power Automation Cyber-Physical-Systems

Juan Sebastian Rodriguez Estupinan

In this thesis, the author proposes a circular system development model which considers all the stages in a typical development process for industrial systems. In particular, the present work shows that the use of virtual prototyping at early stages of the ...

Electro-thermal virtual prototyping of a Rogowski Coil sensor system

Alain Vachoux, Juan Sebastian Rodriguez Estupinan

An electro-thermal model of a Rogowski Coil sensor system is here described. A co-design methodology between VHDL-AMS and Finite Element Analysis (FEA) has been used for modeling the entire system. The proposed modeling strategy uses geometrical FEA to com ...

VHDL-AMS Virtual Prototyping of a Generator Circuit Breaker Ablation Monitoring System

Alain Vachoux, Juan Sebastian Rodriguez Estupinan, Yannick Maret

Generator Circuit Breakers (GCBs) are commonly used in electrical power generation systems to protect key equipment such as transformers and generators from damage due to overload or short-circuit. However the interruption and feeding of high currents lead ...

Eliminating unscalable communication in transaction processing

Anastasia Ailamaki, Frederick Ryan Johnson, Ippokratis Pandis

Multicore hardware demands software parallelism. Transaction processing workloads typically exhibit high concurrency, and, thus, provide ample opportunities for parallel execution. Unfortunately, because of the characteristics of the application, transacti ...

Efficient Modelling and Simulation Methodology for the Design of Heterogeneous Mixed-Signal Systems on Chip

Torsten Mähne

Systems on Chip (SoCs) and Systems in Package (SiPs) are key parts of a continuously broadening range of products, from chip cards and mobile phones to cars. Besides an increasing amount of digital hardware and software for data processing and storage, the ...

VHDL-AMS Model of an Electrochemical Cell to Design VLSI Bio-Chips

Giovanni De Micheli, Yusuf Leblebici, Sandro Carrara, Alain Vachoux

This paper presents a new VHDL-AMS behavioral model of an electrochemical cell suitable for the design of VLSI bio-chips. Existing models are mainly equivalent circuit macromodels using electrical primitives, which hardly fit the actual behavior of biosens ...

Supporting Dimensional Analysis in SystemC-AMS

Alain Vachoux, Torsten Mähne

This paper will introduce new modeling capabilities for SystemC-AMS to describe energy conserving multi-domain systems in a formal and consistent way at a high level of abstraction. To this end, all variables and parameters of the system model need to be a ...

A VHDL-AMS Modeling Methodology for Top-Down/Bottom-Up Design of RF Systems

Alain Vachoux, Torsten Mähne

This paper presents a modelling methodology for the top-down/bottom-up design of RF systems based on systematic use of VHDL-AMS models. The model interfaces are parameterizable and pin-accurate. The designer can choose to parameterize the models using perf ...

SystemC-Based Modeling of Embedded Heterogeneous Systems

Alain Vachoux, Torsten Mähne

SystemC is emerging as a de-facto standard for digital system design. Since embedded systems include more and more heterogeneous components (e.g., analog/RF front-ends, processor cores, embedded software, digital hardware, sensors, actuators), the need for ...

Development of a Bond Graph Based Model of Computation for SystemC-AMS

Yusuf Leblebici, Alain Vachoux, Torsten Mähne

The modelling and simulation capabilities of SystemC-AMS concerning conservative continuous time systems involving the interaction of several physical domains and with digital control components are currently limited. Bond graphs unify the description of m ...

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 ...

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 ...

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

Alain Vachoux

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 ...

VHDL-AMS and Verilog-AMS as alternative hardware description languages for efficient modeling of multidiscipline systems

Alain Vachoux

This paper focuses on commonalities and differences between the two mixed-signal hardware description languages VHDL-AMS and Verilog-AMS in the case of modeling heterogeneous or multi-discipline systems. The paper has two objectives. The first one consists ...

Extending SystemC to Support Mixed Discrete-Continuous System Modeling and Simulation

Alain Vachoux

Systems on chip are more and more heterogeneous and include software, analog/RF and digital hardware, and non-electronic components such as sensors or actuators. The design and the verification of such systems require appropriate modeling means to deal wit ...

Creating Virtual Prototypes of Complex Micro-Electro-Mechanical Transducers Using Reduced-Order Modelling Methods and VHDL-AMS

Torsten Mähne

In this paper the creation of "virtual prototypes" of complex micro-electro-mechanical transducers is presented. Creating these behavioural models can be partially automatised using a reduced-order modelling (ROM) method. It uses modal decomposition to rep ...

Jitter Tolerance Analysis of Clock and Data Recovery Circuits using Matlab and VHDL-AMS

Yusuf Leblebici, Paul Victor Georges Muller

In the scope of the development of a complete top-down design flow targeting clock and data recovery circuits for high-speed data links, we present two methods to analyze the jitter tolerance of such links, based on statistical simulation of incoming data ...
