Modular hierarchical modelling with SIMCOS language

This paper deals with the modular hierarchical modelling and simulation possibilities of the simulation language SIMCOS. After a brief description of the modular modelling possibilities of modern modelling and simulation tools, the emphasis is put on the concept of precompiled dynamic submodels implemented in the SIMCOS simulation language. The simulation processor distinguishes between static, dynamic, continuous discrete, delayed and non-delayed modelling constructs. Thus, a very powerful simulation system with automatic sorting and runtime self-configuration was obtained. The precompiled modelling constructs can be used with textual or graphical modelling. In addition, a preprocessor for hierarchical modelling similar to the macro concept in modern simulation tools was also implemented.
