Abstract
This paper describes a methodology and a frameworkFor building an analyzable real-time model of an object-oriented system that is developed using UML CASEtoo.The real-time models is formulated by a new UMLview named "MAST_RT_View".This view allows thedesigner to gradually build the real-time model accordingto the phase of the development process, to feed data intothe analysis tools, and to bring the relevant timing response back into the model.The MAST_RT_View hasthree models:The processing capacity of the hardware/software platform; the timing behavior of the applicationlogical components; and the workload and the timingrequirement of each real-time situation to be analyzed.This view is analyzable by the MAST set of tools, whichIncludes worst-case schedulability analysis and discrete-event simulation for hard and soft timing requirements.Keywords
