Control Specifications (CSPEC)
The Control Specifications (CSPEC) is used to indicate (1) how the software behaves
when an event or control signal is sensed and (2) which processes are invoked
as a consequence of the occurrence of the event. The control specification (CSPEC)
contains a number of important modeling tools.
The control specification represents the behavior of the system in two ways.
The CSPEC contains a state transition diagram that is sequential specification
of behavior. It also contains a process activation table (PAT) -a combinatorial
specification of behavior.
