Course Introduction:      

   Codesign refers to the simultaneous consideration of hardware and software in the design of an embedded system, rather than the traditional approach of specifying the hardware and constraining the software to fit.  

This course presents codesign as the codevelopment and coverification of hardware and software through the use of simulation and emulation. This codesign begins with a functional design and ends with a detailed Design. Detailed design includes software generation but not hardware fabrication. Traditional embedded system design views the design of software as a separate task from the design of hardware. The purpose of hardware/software codesign is to provide an integrated method. The design work starts from a system description that is not biased. This system description is then refined into software and hardware components. Typically the refinement step is done automatically by synthesizing software and VHDL code from the system description.

The decision about which parts go into hardware and which into software (a process called partitioning) is done by estimating the performance of the system on the system model level. The advantage of this is that it makes it possible to fully explore the design space and find an optimal solution to the design problem.
The design process is based on hardware / software codesign and is no longer partitioned by hardware and software disciplines but rather by the levels of abstraction represented in the system, architecture, and detailed design processes.                                              

Who Should Attend?

This course is designed for project managers who wish to get updated on the latest trends and techniques in embedded system codesign. Software and firmware engineers about to embark on embedded systems design may also attend.

Prerequisites
Core Subject: ES101 Systems Thinking is preferred, although not necessary.

Skills Gained
After completing this training, you will be able to:

• Use the codesign process to design an embedded system of medium complexity.
• Determine the mutual influence of both hardware and software early in the design cycle. Software performance is a key criterion for selecting an architecture.
• Evaluate the enlarged design space. The interoperability of tools and automation of codesign early in the architecture process significantly improves the ability to consider designs that may otherwise be ignored.
• Perform system integration and testing. This reduces effort and resources devoted to integration and testing because hardware and software come from reuse libraries and are coverified.

Training Duration
4 days.
