This package contains the constraints for the Simulink model. These constraints fall in two categories:

• Mandatory Constraints: These constraints must be satisfied for a model to work properly. Due to technical reasons these constraints cannot be checked during model build.
• Optional Constraints: Optional constraints are constraints that are valid for actual Simulink models but must not be satisfied for the Simulink library to work. An example is a constraints that requires line not to cross subsystem boundaries. This is required in Simulink but this library allows subsystem flattening and thereby cross-subsystem lines.
