Project 1- Traffic Jam Assistant Feature
AIM: Develop a Traffic Jam Feature model as per the MBD guidelines, create SLDD, model advisory report and code generation using embedded coder
Steps Involved:
1. SLDD is created and linked to the model
Goto-->model properties-->external data-->new-->TrafficJamFeature_modeldd.sldd
2.Solver configuration settings:
Goto model settings-->configuration parameters-->solver type 'Fixed'-->solver 'discrete(no continuous states)'-->step size to 0.01
3. MATLAB Simulink model is developed as per the requiremnts
4. All input and output signals are resolved at their origin point and propagated at their inner stage
Here screen shots are shared for one input and output
5. Code Generation settings
Goto model settings-->configuration parameters-->code genaration-->system target file 'ert.tlc'
6. Model Advisor Report Generation:
Model Advisor Check completed with 10 warnings and 134 checks passed and report is attached
7. Code generation:
Goto APPS-->Embedded coder--> C Code-->Build
