....n possible combinations which have to be checked in the worst case. More information about code generation for Modelica hybrid simulation can be found in [11] Modeling ideal friction in Modelica is described in [15] and [11] The technique of parameterized curve descriptions was introduced in [3] and a series of related papers. However, no proposal was given how to actually implement such models in a numerically sound way. In Modelica the (new) solution method follows logically because the equation based system naturally leads to a system of mixed continuous discrete equations which have ....

....semiconductor FETs) line models . ideal elements (switch, diode, opamp, transformer et al. The symbols of most of the components correspond to the standard [10] Some of the symbols can be seen in fig. 1. 2 Formulation Principles The underlying modelling concept is n pole approach [1]. The components are taken as n poles which interact with their surrounding network part via their n pins. At each pin the electrical quantities current and voltage are defined. After the pins are defined the model equaFigure 1: Components of the Modelica package Modelica.Electrical.Analog. ....

....are components of the library. The real diode (Diode) is a semiconductor device. Its current voltage characteristic is an exponential function which is continuated linearly above a certain exponent which is the parameter Maxexp. The ideal diode (IdealDiode) uses the declarative description method [1], 8] 9] If the parameters Roff, and Gon are zero the ideal diode is an idle running branch in the open case, and a chort cut in the clodes case. The following simple circuit uses both of the diodes. The parameter are chosen such that differences in the diode behaviour can be seen easily. ....

....4.1 1: Some simulators with behavioral modeling capabilities 4.2. A Modeling Approach In addition to a mixed signal modeling language a mathematically founded modeling approach is necessary [17, 18] We propose a method which is based on the terminal behavior description of components subsystems [19]. One of the main ideas of this approach is the separation of the terminals into six classes or types of terminals (see Figure 4.2 1) A electrical pins with terminal voltages v a and controlled (dependent) terminal currents i a : modeling voltage current relations in conventional nodal ....
