Description

Description

This course provides an in-depth exploration of UML (Unified Modeling Language) for embedded and real-time systems. Participants will learn how to apply UML and its real-time extensions across analysis, design, and coding phases for embedded system development.

Trainees will develop a model for a realistic real-time embedded system based on its requirement specification using Papyrus (an Eclipse-based UML tool) or, upon request, Enterprise Architect – Professional Edition.

Training Objectives

• Understand the unique mechanisms of embedded and real-time systems
• Learn how to use UML with real-time extensions for system analysis
• design
• and implementation
• Develop practical UML models for embedded systems throughout the course
