It supports the whole process of program development, i.e. from the abstract specification to the efficiently executable program in a formal, precise and convenient way. The steam boiler control specification problem, a large case study in the fields of real time, hybrid and communication systems, is discussed with XYZ/E. The approach covers physical model construction, formal specification, stepwise refinement, verification, executable program and visual user interface programming.展开更多

The temporal logic language XYZ/E can represent both high level and low level specifications in the same framework, so that the specification and implementation of software systems are very convenient. A specification and an implementation of the Steam Boiler Control Specification Problem in XYZ/E is presented in this paper. A visual user interface is also implemented.展开更多
文摘The TLL XYZ/E is a formal language able to represent the dynamic semantics and the static semantics in a unified framework.
