The Reach/Coreach Tool tracks and highlights data flow and control flow in the model. The tool identifies, for some specified Simulink blocks, parts of the model that depend on those blocks (Reach functionality), or parts of the model that the specified blocks depend upon (Coreach functionality). After the dependencies have been identified, the extraneous blocks can be removed via the tool's model slicing function.

• For installation instructions and instructions on how to use the tool, please see the included Reach-Coreach/doc/ReachCoreach_UserGuide.pdf.

• This tool relies on our Simulink Utility. Please download it here:
