A logic-based requirements language for the specification and analysis of real-time systems

The applications of real-time systems have dramatically increased over recent years. Requirements for real-time systems need to specify timing constraints. In this paper, we augment the FRORL requirements specification language with constructs specifically geared towards capturing requirements of real-time systems. We give meaning to these constructs through temporal logic. The non-functional aspects of a specification such as temporal properties asserted of a real-time system and the consistency of timing constraints can be verified through model checking and graph-theoretical algorithms.
