Abstract
Abstract This paper considers the use of the formal methods CSP and Timed CSP in the specification, design and verification of a hard real-time industrial application. The application involves the control of a slider inserting periodically into the periphery of a high speed drum. A specification for the hazard free operation of the system is formulated and two models are introduced, one with timing constraints and the other without. The safety and liveness properties of the models are contrasted and three semantic domains.(the Traces model, the Failures model and the Timed Failures model) are employed to show that the design satisfies the specification . The suitability of the design is assessed.
