ModelLib: A Web-Based Platform for Collecting Behavioural Models and Supporting the Design of AMS Systems

This paper describes ModelLib, a web-based platform for collecting models from different domains (e.g. electrical, mechanical) and levels of abstractions. Use cases for this tool are presented, which show how it can support the design~process of complex AMS systems through better reuse of existing models for tasks like architecture exploration, system validation, and creation of more and more elaborated models of the system. The current state of the implemented ModelLib prototype is described and an outlook on its further development is given

Supporting Dimensional Analysis in SystemC-AMS

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 annotated with their measurement units in such a way that they become intrinsic part of the data type. This enforces correct model assembly through strict interfaces and coherent formulas describing the analog behavior by means of dimensional analysis. A library of generic block diagram components has been developed to demonstrate how both requirements can be met using the Boost libraries together with SystemC- AMS. The demonstrated implementation techniques are the key to integrate new Models of Computation (MoCs) into SystemC-AMS to facilitate further the description of multi-domain systems

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

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 physical domains and their interaction with nonconservative digital control components. Bond graphs unify the description of multi-domain systems by modelling the energy flow between the electrical and non-electrical components. They integrate well with block diagrams describing the signal processing part of a system. It is proposed to develop an extension to the current SystemC-AMS prototype, which shall implement the bond graph methodology as a new Model of Computation (MoC)

Fostering the Reuse and Collaborative Development of Models in the AMS SoC Design Process

Systems-on-Chips (SoCs) integrate more and more heterogeneous components: analog/RF/digital circuits, sensors, actuators, software. For the design of these systems very different description formalisms, or Models of Computation (MoCs), and tools are used for the different subblocks and design stages, which often create interoperability problems. Additionally the verification of a complete SoC is difficult due to huge performance problems. The goal of this Ph.D. work is to develop an efficient modeling and simulation platform that supports the design of mixed-signal SoCs using component models written in different design languages and using different MoCs. One component of this work is the development of a web-based platform for collecting behavioral models and supporting the design of Analog and Mixed-Signal (AMS) SoCs. Its current state and an outlook on its further development is the focus of this paper

Analog and Mixed-Signal Modelling with SystemC-AMS

SystemC will become more and more important for the design of digital circuits from the specification down to the RT-Level. Complex systems often contain analog components. This paper introduces concepts for the extension of the SystemC methodology for the specification and design of analog and mixed signal systems. The concepts will be illustrated on a telecommunication system including digital hard- and software, analog filter and an analog environment

Support pour l'analyse dimensionnelle en SystemC-AMS

La modélisation de systèmes hétérogènes conservatifs multi-domaines (électrique, mécanique, fluidique, etc.) requiert un moyen de vérifier que les quantités manipulées par les modèles aient des unités cohérentes. Nous présentons ici les fondations pour le support de l'analyse dimensionnelle statique (effectuée à la compilation) de modèles développés à l'aide des extensions AMS (Analogue and Mixed-Signal) de SystemC. L'approche présentée dans ce papier sera incorporée dans un nouveau modèle de calcul Bond Graph qui complétera les modèles de calcul déjà prévus dans les extensions AMS de SystemC

Finally, some preliminary seed work is presented and the outline of the analog and mixed-signal extensions development work is given
