Simulink User Interface

Simulink Library Browser

The Library Browser displays the Simulink block libraries installed on your system. You build models by copying blocks from a library into a model window.

Tips for Using the Library Browser

When using the Library Browser, note the following:

Standard Block Libraries

Simulink software provides 16 standard block libraries. The following table describes each of these libraries.

Block LibraryDescription
Commonly Used BlocksContains a group of the most commonly used blocks, such as the Constant, In1, Out1, Scope, and Sum blocks. Each of the blocks in this library are also included in other libraries.
ContinuousContains blocks that model linear functions, such as the Derivative and Integrator blocks.
DiscontinuitiesContains blocks with outputs that are discontinuous functions of their inputs, such as the Saturation block.
DiscreteContains blocks that represent discrete time functions, such as the Unit Delay block.
Logic and Bit OperationsContains blocks that perform logic or bit operations, such as the Logical Operator and Relational Operator blocks.
LookUp TablesContains blocks that use lookup tables to determine their outputs from their inputs, such as the Cosine and Sine blocks.
Math Operations Contains blocks that perform mathematical and logical functions, such as the Gain, Product, and Sum blocks.
Model VerificationContains blocks that enable you to create self-validating models, such as the Check Input Resolution block.
Model-Wide UtilitiesContains blocks that provide information about the model, such as the Model Info block.
Ports & SubsystemsContains blocks that allow you to create subsystems, such as the In1, Out1, and Subsystem blocks.
Signal AttributesContains blocks that modify the attributes of signals, such as the Data Type Conversion block.
Signal RoutingContains blocks that route signals from one point in a block diagram to another, such as the Mux and Switch blocks.
SinksContains blocks that display or export output, such as the Out1 and Scope blocks.
SourcesContains blocks that generate or import system inputs, such as the Constant, In1, and Sine Wave blocks.
User-Defined FunctionsContains blocks that allow you to define custom functions, such as the Embedded MATLAB™Function block.
Additional Math & DiscreteContains two additional libraries for mathematical and discrete function blocks.

Simulink Model Window

The model window contains the block diagram of the model. You build models in the model window by arranging blocks logically, setting the parameters for each block, and then connecting the blocks with signal lines.

The model window also allows you to:
