Important Characteristics of VHDL-AMS and Modelica with Respect to Model Exchange

Behavioral Modeling and Simulation of Semiconductor Devices and Circuits Using VHDL-AMS

During the past few years, a lot of work has been done on behavioral models and simulation tools. But a need for modeling strategy still remains. The VHDL-AMS language supports the description of analog electronic circuits using Ordinary Differential Algebraic Equations (ODAEs), in addition to its support for describing discrete-event systems. For VHDL-AMS to be useful to the analog design ...

Enforcing model composability in Modelica

Modelica provides intuitive constructs to create and group model definitions. However, models themselves do not compose. In other words, the connection of type-compatible and locally balanced submodels does not generally yield a valid (e.g., balanced, structurally non-singular) model. Starting from simple examples of such invalid models (resulting from commonly encountered situations when using...

Mixed Domain Modeling in Modelica

Modelica is a language for convenient, component oriented modeling of physical systems. In this article an overview of the language, available libraries, the Dymola simulator and some industrial applications is given. Additionally, a comparison of Modelica with VHDL-AMS is presented.

Automatic Modelling Approach for Power Electronics Converters: Code Generation (C S Function, Modelica, VHDL-AMS) and MATLAB/Simulink Simulation

Physically Oriented Modeling of Heterogeneous Systems

Abstract. Technical systems can be characterized very often as complex heterogeneous systems. Many simulation algorithms exist for the analysis of continuous and discrete systems. However, the first modeling steps in the physical domains have not been sufficiently assisted by CAD tools. Multiports and generalized KIRCHHOFF’s networks proved to be powerful concepts in a physically oriented model...
