The design and implementation of the [mu]Modelica compiler /

Modelica is a recently developed object-oriented language for physical systems modeling. It is a modern language built on non-causal modeling with mathematical equations and object-oriented constructs.An open source research prototype compiler for muModelica, a subset of Modelica, is presented. The compiler takes textual Modelica source as input, translates it into flat Modelica, then performs a series of symbolic transformations on the differential-algebraic equations, most notably, assigning causality, and generates input suitable for processing by a numerical simulator such as Octave.Design and implementation issues of the muModelica compiler are discussed in some detail in this thesis. These issues include the general architecture of the compiler, semantic analysis, formula manipulation, and code generation. Some advanced formula manipulation techniques are also studied, and are proposed to be implemented as future work
