Cleopatra Physically-correct Speciications of Embedded Real-time Programs

چکیده
The backbone of our methodology is the Time constrained Reactive Automaton TRA formalism which adopts a fundamental notion of space and time that restricts expres siveness in a way that allows the speci cation of only reactive spontaneous and causal compu tation Using the TRA model unrealistic sys tems possessing properties such as clairvoy ance caprice in nite capacity or perfect timing cannot even be speci ed We argue that this ounce of prevention at the speci cation level is likely to spare a lot of time and energy in the development cycle of responsive systems not to mention the elimination of potential hazards that would have gone otherwise unnoticed

Building Responsive Systems from Physically-correct Speciications
Predictability { the ability to foretell that an implementation will not violate a set of speciied reliability and timeliness requirements { is a crucial, highly desirable property of responsive embedded systems. This paper overviews a development methodology for responsive systems, which enhances predictability by eliminating potential hazards resulting from physically-unsound speciications. T...

Tutorial material for FME'96: The goal of the Provably Correct Systems project (ProCoS) is to develop a mathematical basis for development of embedded, real-time, computer systems. The tutorial focuses on the need to link the diierent formalisms that are used in a development path from speciication of requirements to executable programs or specialized hardware. General linking paradigms for com...
