Steps for Production Code Generation
Used for continuous verification– With each change, verify results
are still acceptable Test data generated using
full model and signal logging Script used to compare results

Steps for Production Code Generation
Discrete integrators needed for embedded controllers– Replaced using Model Discretizer
Step-size adjusted formaximum speed and acceptable accuracy– Parameterized with MATLAB variables

Steps for Production Code Generation
Data types assigned to variablesto specify memory allocationon controller
Storage classes are assignedto variables to define how theyare implemented on the target– Global, pointers, etc.
– Decouples model from embedded target
