MATLAB & Simulink

EMBEDDED SYSTEMS AND FPGA DESIGN

Testing Generated Code in Simulink

Course Highlights

This is a one-day course that provides a working introduction to designing and testing embedded applications with Simulink® Coder™ and Embedded Coder®. Themes of simulation speedup, parameter tuning in the deployed application, structure of embedded code, code verification, and execution profiling are explored in the context of model-based design. Topics include:

​

  • Simulation Speedup with Code Generation

  • Parameter Tuning with External Mode

  • Code Generation

  • In-the-Loop Verification

  • Code Execution Profiling

Prerequisite

Working experience with Simulink is compulsory. Simulink® for System and Algorithm Modeling (or Simulink for Automotive System Design) can be taken to satisfy the prerequisite. Knowledge of C programming language is strongly recommended to learners who want to benefit from code inspection.
