To add blocks to the current model, open the Simulink Library Browser and drag the block onto the design canvas of the Simulink editor. Open the Library Browser by clicking the button on the Simulation tab. The standard Simulink library of blocks displays, as well as the HLS library in the AMD Toolbox.

Tip: You can also open the Library browser by typing the slLibraryBrowser command from the command prompt.

The library organizes HLS blocks into sub-categories based on functionality. The following figure shows the HLS > Logic and Bit Operations block library in the Library Browser.

Double-clicking a block in the Library Browser opens the Block Parameter dialog box. This displays the default values for the various parameters defined on the selected block. While the block is in the library, you can only view the parameters. To edit the parameters, you must add the block to the design canvas.

To get additional information about a block, right-click the block in the Library Browser and select the Help command. Alternatively, you can double-click the block in the Library Browser and click the Help button from the block dialog box. The Help browser opens with block-specific information.

Dragging and dropping the block onto the canvas adds the block to the model with the default parameter values defined.

Tip: You can quickly add blocks to your model. Single-click the Simulink Editor canvas, then type the block name. Simulink displays possible matches from the libraries, and you can select and add the block of interest.

Simulink models contain both signals and parameters. Signals are represented by the lines connecting blocks. Parameters are coefficients that define key characteristics and behavior of a block.
