About Block Libraries
A block library is a collection of blocks
that serve as prototypes for cloning blocks to Simulink models. Simulink provides
a Library Browser that you can use to display block libraries, search
for blocks by name, and clone library blocks into models. All installed
libraries appear in the Library Browser when you open it. See Populating a Modelfor
information about how to use the Simulink Library Browser.
Simulink comes with two
built-in block libraries: the Simulink block library and the Real-Time Workshop block
library. The latter is included with Simulink to support sharing
models that contain Real-Time Workshop blocks. Many additional
products and associated block libraries are available from The MathWorks™.
See the MathWorks Web Site for
product information. You cannot change a built-in block library in
any way.
When you clone a block from a library into a model, Simulink does
not copy the library block itself. Instead, Simulink places a reference
block in the model, and connects the reference block to
the library block using a library link. The library
block is then the prototype block, and the prototype
representation in the model (via the reference block) is a block
instance. The appearance and behavior of a linked block
are the same as if you had actually copied it to the model. For most
purposes, you can ignore the underlying and link and reference block
structure and just think of a block cloned from a library as a block
instance.
