In working

Automatically find differences between Simulink models. ModelDif compares two Simulink model files for additions, deletions, and changes to blocks, lines, configuration parameters, model properties, subsystems, and annotations. In other words, it computes differences that affect the logic of the model, not simple layout changes.
 
 

View Differences Graphically
ModelDif presents differences in a list or as highlighted blocks right within Simulink. When a difference is selected from the list, the corresponding block or line will flash on the diagram in Simulink. You can configure what colors to use for additions, deletions, and changes.
 

Configurable
ModelDif is flexible. It allows you to specify that certain blocks or line attributes be included or excluded from the comparison. It also allows you to do the same for configuration parameters, model properties, and annotations.
 

Command-Line Interface
ModelDif's command-line interface makes it easy to execute ModelDif from scripts.
