Animation in CONRAD: informal analysis of timing properties

Abstract

It is suggested that timing restrictions are the fundamental part of the specification of a time-critical system (limiting the possible design solution space), because most of the timing restrictions have been objectively determined by the object to be controlled and thus cannot be changed arbitrarily. Timing correctness in real-time systems means that process activations, data production and consumption take place in time). So as to guarantee this, methods are needed to formally specify various timing properties and prove correctness of the specification. Equally important, however, are methods and tools for informal study of timing properties. Special emphasis is placed on the possibilities provided by the ANIMATOR., which is one of the two main tools in the CONRAD software engineering environment.<>
