Other C- and h-files are generated for the model to specify a header-file, the base

types, e.g. Int32, and the data types, e.g. CONTINUOUS in the example code

above.

TargetLink also provides powerful simulation capabilities to analyse fixed-point

quantization and overflow effects which is done by choosing to simulate using the

generated code using Software In the Loop, SIL, simulation. The code can also be

run on the target directly using Process In the Loop, PIL, to validate the controller

designs directly on the target.

Real-Time Workshop Embedded Coder is a separate, additional product for use in

Matlab/Simulink environment. RTW EC generates code from Simulink and

Stateflow models. For fixed-point simulation and code generation an additional

tool is required, that is the Fixed-Point Toolbox. Code can be generated by a

simple click for both fixed-point and floating-point. To run the code directly on

the target some modifications are required to the Embedded Real-Time target files

provided by RTW EC.

RTW EC generates code directly from Simulink model and no conversion is

necessary.
