Rules and Guidelines for Complex Data Type Definitions

Rules and Guidelines for Complex Data Type Definitions

Consider the following rules and guidelines when you work with complex data type definitions:
  • A struct port or a struct element in a complex port must reference a complex data type definition.
  • You cannot reference a complex data type definition in one mapping to a complex port in another mapping.
  • You cannot reference a recursive data type definition to a struct port or a struct element in a complex port.
  • Changes to the elements in a complex data type definition are automatically propagated to complex ports that reference the complex data type definition.
  • If you change the name of the type definition library or the complex data type definition, you must update the name in expressions that use complex functions such as STRUCT_AS, RESPEC, and CAST.
