Subsystem Component Name
When you add a subsystem component to a system definition file, you are
selecting a system from a list of systems that you have already defined. By
default, the name of the subsystem component is the name of the referenced
system.
After a subsystem component is added to a system, you can rename it. The name
can be any length and can contain spaces. A subsystem component name must be
unique because the IFD does not accept duplicate component names within a
system file.
Execution Settings
A subsystem component has a defined set of interfaces that are based on the
sources and targets (inputs and outputs) of the various maps that it contains. The
inputs and outputs of a subsystem are derived according to the following rules.
♦ An input of a subsystem is a source that is not internally produced by one of its
components.
♦ An output of a subsystem is a target that is internally produced by one of its
components, and is not deleted.
