An approach to specification of requirements and verification of design for real-time systems is presented, A system is defined by a conventional mathematical model for a dynamic system where application specific state variables denote total functions of real time. Specifications are formulas in a real-time interval logic, where predicates define durations(More)
The goal of the Provably Correct Systems project (ProCoS) is to develop a mathematical basis for development of embedded, real-time, computer systems. This survey paper introduces the speciication languages and veriication techniques for four levels of development: Requirements deenition and control design; Transformation to a systems architecture with(More)
Embedded systems use specialized hardware devices to interact with their environment, and since they have to be dependable, it is attractive to use a modern, type-safe programming language like Java to develop programs for them. Standard Java, as a platform-independent language, delegates access to devices, direct memory access, and interrupt handling to(More)
