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 ...

Hydrological forecasting model in Colombia: application to the Magdalena River

André Musy, Bettina Schaefli, Richard Metzger

The development of a hydrological forecasting model is conditioned by the available data collected in the entire hydrological catchment for which discharge has to be predicted. The forecast quality not only depends on the available historical data but also ...

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

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 ...

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 ...

SystemC-AMS Requirements, Design Objectives and Rationale

Alain Vachoux

This paper presents and discusses the foundations on which the analog and mixed-signal extensions of SystemC, named SystemC-AMS, will be developed. First, requirements from targeted application domains are identified. These are then used to derive design o ...
