Key Semantics of Parametric Diagrams

• Constraint Definitions • Represented as nodes • Display dependent variables and equations

• Mappings between system parameters

• Represented as lines connecting nodes • Labeled with local variable / parameter name at each end • Architecture entity parameters • Displayed as boxes on the frame or as rectangular blocks labeled with the parameter name
