In order for a requirement specification to be useful in systems development, the specification language must exhibit various features which contribute to the ease and user friendliness of the specification process [Tse91]. 2.2 Common Families of Formal Specification Languages The most commonly encountered families of formal specification languages are modeloriented and property oriented techniques [Wi90] Using a model oriented method, a specifier defines a system s behavior directly by constructing a model of ....

....devices, their hierarchy of responsibility, and the communication paths between them.

It has a graphical editor for directly capturing a design s abstract architecture. The graphical information never needs to be regenerated as text by the designer. Instead, other software in the PICSIL suite ....
