Dataflow diagrams (DFDs) are modeled as networks of concurrent processes. With the use of the temporal logic language XYZ/E, the formal basis of the semantic specification of DFD can be ensured, and the system properties such as safety and liveness can be easily characterized. A verification methodology is proposed which is based on the formal semantics of DFD. The implementation of the tools which can support the formal specification, verification, and simulation of DFD are also briefly described
