What is the difference between a Simulink library and a model reference?
So far, I found 2 difference betweem them. is it right?
Reference
1.With model reference, you can also select acceleration methods
(it basically compiles the model)
=> performance improvement
2.Model references allow partial builds when using the coder product.
=> performance improvement
Library
-
Is there more difference about two except these?
Thank you

For Clarification, I used Libary for one function(like battery monitoring module) in a one project same as model reference.

Hi Jaeha
Yes, there are additional differences between "Simulink libraries" and "model references" beyond the ones you have mentioned.
Here’s a more comprehensive comparison:
Simulink Library:
1. Purpose: Reusable blocks for consistency across models.
2. Reusability: Centralized updates to library blocks affect all instances.
3. Customization: Limited to parameter changes unless link is broken.
4. Performance: No inherent performance boost.
5. Version Control: Easier for individual blocks.
Model Reference:
1. Purpose: Hierarchical model structuring for complex systems.
2. Modularity: Independent development and testing of components.
3. Performance: Supports acceleration and partial builds for speed.
4. Code Generation: Better for incremental code generation.
5. Encapsulation: Treats models as black boxes, reducing conflicts.
6. Version Control: Easier for entire models.
Hope this helps!
