12. Operational System
Component type and component implementation declarations are architecture design elements that define the structure and connectivity of a physical system architecture.  They are component classifiers that must be instantiated to create a complete system instance.  A complete system instance that represents the containment hierarchy of the physical system is created by instantiating a root system implementation and then recursively instantiating the subcomponents and their subcomponents.  Once instantiated, a system instance can be completely bound, i.e., each thread is bound to a processor; each source text, data component, and port is bound to memory; and each connection is bound to a bus if necessary.
A completely instantiated and bound system acts as a blueprint for a system build.  Binary images are created and configured into load instructions according to the system instance specification in AADL.
