The design of real-time systems: from specification to implementation and verification

Presents an engineering approach to the design of distributed real-time systems, which guarantee hard deadlines and can tolerate a specified set of faults. The methodology covers the stepwise refinement of the given requirements, expressed in the form of real-time transactions, to task and protocol executions. It also includes a timing analysis and dependability evaluation of the still incomplete design. The testability of the evolving system is considered to be of essential concern. A set of coherent tools for the support of the methodology is described in some detail. The methodology assumes that the runtime architecture is based on static scheduling, and a globally synchronised time-base is available to co-ordinate the system actions in the domain of real time
