Choose a Componentization Technique for Code Reuse

Key componentization techniques that you can use with Simulink^® and the code generator to produce reusable code include:

• Referenced models

• Subsystems

• Library subsystems

• Combinations of models, subsystems, and library subsystems

Choose componentization techniques based on your code reuse goals.

Goal	Referenced Model	Subsystem in Model	Subsystem in Library
Design for explicit code reuse.	√	√	√
Facilitate parallel team development.	√	√	√
Reuse function within a model or across models.	√
Reduce build time by generating reusable code incrementally.	√
Verify reusable code with SIL or PIL simulation.	√
Optimize generated code by configuring code generator to detect opportunities for code reuse.	√	√	√
Maximize reuse with context-dependent behavior.		√	√
Develop a frequently used, and infrequently changed, utility function.			√
