Timing Analysis of Automatically Generated Code by MATLAB/Simulink

Abstract — In the development of a real-time embedded control system it is necessary several types of professionals. The control engineer’s tool is the functional block diagram, since it describes the mathematical models of the controller being designed. Many development tools that use block di-agrams also automatically generate code. The objective of this work is to show how it is possible to evaluate, through an algebraic model, the timing behavior of the multitask system generated automatically by Simulink/MatLab, to-gether with its real-time microkernel. This modeling allows the control engineer a better understanding of the timing behavior of the tasks, including the identification of delay and jitter problems. I
