  • The development of this library was strongly motivated by the master thesis of Isolde Dressler (see literature), in which a compiler from JGrafchart to Modelica was designed and implemented. This project was supervised by Karl-Erik Årzén from Department of Automatic Control, Lund Institut of Technology, Lund, Sweden.
  • This library profits also from the experience gained in the focused research program (Schwerpunktprogramm) "Continuous-Discrete Dynamic Systems" (KONDISK), sponsored by the Deutsche Forschungsgemeinschaft under grants OT174/1-2 and EN152/22-2. This support is most gratefully acknowledged.
  • The implementation of the basic components of this library by describing finite state machines with equations is based on (Elmqvist, Mattsson and Otter, 2001), which in turn uses ideas from (Mosterman, Otter and Elmqvist, 1998), see literature
