Course Description and Objectives

This is a project-based course focused on systems development with an emphasis on analysis and design of real-time systems. The course starts by introducing the Unified Modeling Language for real-time systems and describing their characteristics and unique attributes of real-time safety critical systems. The object-oriented development process for embedded systems is described. The analysis and design phases of development are then covered by describing object modeling techniques and design patterns and frameworks. The dourse concentrates on pattern-oriented analysis and design. The POAD process and its application to several case studies will be addressed.

A computer-aided software engineering tool is used throughout the course. A term project, in-class exercises, and a mid-term examination are used to assess the students learning process. The term project is to be done in teams of three-four students. Project presentations and reviews will be conducted in class.

Expected Learning Outcomes

Upon successful completion of this course students will be able to:

1. Specify the characteristics of real-time software and identify unique attributes and problems related to the software development for real-time systems using specific examples.
2. Use a CASE tool to:

• Correctly analyze the software requirements of a complex real-time system and develop a specification based on object-oriented analysis and
• Develop and a high level design according to the specification using design patterns.

Specify and practice the usage of key object-oriented design patterns in real-time systems.

Identify a process for Pattern Oriented Analysis and Design.

Develop and document a real-time system design using the POAD process.

• Mid-term Exam: 35%
• Project: 35%

The project will be conducted by groups of three-four students. Project reviews and reports will be required from each group. The final report should summarize the whole project and document problems encountered and lessons learned during the software analysis and design process. It is expected that students will participate equally in the work of the group. Group meetings minutes specifying the attendees should be included, and the contribution of each student must be documented in each report.

Grading Policy

No make-up exams except by prior arrangement with instructor.

Late assignment = no assignment.

Exam grading appeals in writing on the day the exam is returned.
