SystemC 2.0 Language ArchitectureFigure 1 below summarizes the SystemC 2.0 language architecture.
There are several important concepts tounderstand from this diagram.All of SystemC builds on C++.Upper layers within the diagram are cleanly built on top of the lower layers.
The SystemC core language provides only a minimal set of modeling constructs for structural description,concurrency, communication, and synchronization.Data types are separate from the core language and user-defined data types are fully supported.
Commonly used communication mechanisms such as signals and fifos can be built on top of the corelanguage. Commonly used models of computation (MOCs) can also be built on top of the core language.
