Code Reuse

Design models from which code generator produces reusable function code

Simplify software distribution and reduce the time and resources required to develop software by designing models from which you can generate reusable code. Use key Simulink^® componentization techniques to partition a model into design components that you simulate, generate code for, and verify independently. The code generator produces reusable function code from referenced models, subsystems, and library subsystems.
