چکیده

In this paper we address some aspects of the “UML Profile for Schedulability, Performance and Time” (SPT), that have been found to be improvable. In particular, we describe problems and possible solutions related to the usage of the profile in the representation of schedulability analysis models for real-time distributed systems. The issues appear mainly from a comparison between the SPT and the concepts used in MAST (Modeling and Analysis Suite for Real-Time Applications).

The UML – MARTE Standardized Profile

The UML Profile for Modeling and Analysis of Real-Time and Embedded Systems (also called the UML profile for MARTE, or simply, MARTE) adds capabilities to UML for model-driven development of real-time and embedded systems (RTES). It provides support for specification, design, and verification/validation stages. This new profile replaces the existing UML Profile for Schedulability, Performance a...

Experiencing the UML profile for MARTE in the generation of schedulability analysis models for MAST

This short paper presents the design, implementation, and initial results of a tool that extracts from UML models the schedulability analysis data that are necessary for the application of the MAST set of tools on them. The input analysis models represent concurrent, distributed real-time systems that are formalized in UML annotated with the extensions proposed by the UML Profile for MARTE; the...

Integrating Real-Time UML Models with Schedulability Analysis

The integration of schedulability analysis with the industry standard Unified Modeling Language (UML) allows real-time developers to detect, at an early stage of development, unfeasible (unschedulable) real-time architectures. It, thus, prevents costly design mistakes and accelerates development schedules. This integration, accomplished through the timing extensions of UML, also allows the deve...

High level modeling for Real-time applications with UML & MARTE

This paper shows initial results and the research path in a methodology to use UML & the UML Profile for MARTE in the design of real-time applications. The modeling constructs used are those proposed in the High Level Application Modeling chapter of the MARTE standard. These elements are at a high abstraction level, and hence they need to be complemented with a number of constraints and rules o...

Issues in Mapping from UML Real-Time Profile to OSEK API

UML Profile for Schedulability, Performance and Time is designed to add standard real-time extensions to UML in order to facilitate real-time analysis capabilities, such as rate monotonic analysis, based on the profile. In this paper we explore issues involved in generating code for the OSEK API, which is a popular realtime operating systems standard in the automotive industry.
