About Block Libraries

Libraries are collections of blocks intended to serve as prototypes for creating instances of block types in models. Simulink^® software uses a special type of model file to store block libraries.

You create instances of block types by dragging and dropping or copying library blocks into models. When you copy a library block into a model, Simulink software creates a link between the instance, called a reference block, and its prototype in the library. The link allows changes in the prototype to propagate automatically to the instances in a model. Libraries ensure that your models automatically include the most recent versions of blocks developed by yourself or others.

Simulink comes with a library of commonly used block types called the Simulink block library. See Starting the Simulink^® Engine for information on displaying and using this library. Additional libraries are available from The MathWorks. You can also create your own block libraries (see Creating Block Libraries ).

Note   Although the Real-Time Workshop® block library is provided with Simulink to enable model sharing, help for blocks in that library is available only if you have a Real-Time Workshop license.
