    1. Model Based Design of Embedded Systems Prof. Jerzy W. Rozenblit Dept. of Electrical and Computer Engineering The University of Arizona Tucson, Arizona 85721 U.S.A.

    2. 2 Outline Introduction and Motivation Conventional Design Approach Model-based Methodology Requirements Driven Test Scenario Generation Tool Support Summary

    3. 3 Goals and Contributions Establish a framework for model-based design of embedded systems Defined embedded systems design as a systems modeling problem Address the model continuity problem Developed a process which transforms design models into mixed HW/SW implementations – model compilation Develop a new testing approach

    4. 4 Traditional Design Immediate partitioning into HW and SW. Hardware and software threads are pursued separately. Emphasis is stronger on hardware than software. Belief that HW and SW components can be developed separately; that inadequacies in HW can be compensated SW revisions.

    5. 5 Codesign Hardware/Software Codesign refers to a simultaneous consideration of hardware and software aspects in the design of computing systems Model-based approach provides for early system assessment through executable, implementation independent, models Addresses the inability to evolve system level models gradually into efficient hardware/software implementations – (model continuity problem)
