Thesis Topic: The Design and Implementation of the ╬╝Modelica Compiler

Abstract: Modelica is a recently developed object-oriented language for modeling of large, complex, and heterogeneous physical systems. It is a modern language built on non-causal modeling with mathematical equations and object-oriented constructs.

I have built a research prototype compiler for μModelica (a subset of Modelica) in my M.Sc. thesis. The μModelica compiler is focused on non-causal modeling, which is the real essence of Modelica. It 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.

For a detailed description of the design of my compiler, please refer to my thesis.
