HDL Code Generation Options in the Configuration Parameters Dialog Box
The following figure shows the top-level pane in the Configuration Parameters dialog box. To open this dialog box, in the Apps gallery, click HDL Coder. TheHDL Code tab appears. In the Prepare section, click Settings.
Note
When the pane of the Configuration Parameters dialog box appears, clicking theHelp button displays general help for the Configuration Parameters dialog box.
HDL Code Tab in Simulink Toolstrip
The Simulink® Toolstrip contains contextual tabs that appear only when you need to access them. To access the HDL Code tab, open the HDL Coder app from the Apps tab on the Simulink Toolstrip.
The HDL Code tab provides shortcuts to the HDL code generation options. You can also use this tab to initiate code generation.
Options include:
- : Open the HDL Workflow Advisor.
- : Open the HDL-compatible block library in the Simulink Library Browser or open the HDL Block Properties dialog box for a block that you select in your model.
Note
After you open the HDL-compatible block library, to restore the Library Browser to the default view, in the Library Browser, click the
button. - : Open the HDL Code Advisor for the model or the selected Subsystem.
- : Open the HDL Code Generation pane in the Configuration Parameters dialog box.
- : Open the > pane.
- : The HDL configuration component is internal data that HDL Coder™ creates and attaches to a model. This component lets you view the HDL Code Generation pane in the Configurations Parameters dialog box, and use theHDL Code Generation pane to set HDL code generation options. To remove the HDL Code Generation configuration component to or from a model, select this option. For more information, see Add or Remove the HDL Configuration Component.
- : Select the top-levelSubsystem or model for which you want to generate HDL code. This option corresponds to the Generate HDL for option in the HDL Code Generation pane of the Configuration Parameters dialog box.
- : Initiate HDL code generation; equivalent to the check box in the > > tab of the Configuration Parameters dialog box.
- : Select a block in your model and navigate to the HDL code generated for that block. To use this setting, you must have generated a traceability report.
- : Opens the Code Generation Report if this report exists on the path. Otherwise, this button opens the HDL Check Report.
- : Initiate test bench code generation; equivalent to the button in the Configuration Parameters dialog box. To use this button, you If you do not select a subsystem in the Generate HDL for menu, the Generate Test Bench menu option is not available.
If you have HDL Verifier™ installed, you can generate a HDL cosimulation model or aSystemVerilog DPI component. - : Generate a protected model that you can share with a third party without revealing the intellectual property of the model.
HDL Code Options in the Block Context Menu
When you right-click a block that HDL Coder supports, the context menu for the block includes an submenu. The code generator enables items in the submenu according to:
- The block type: for subsystems, the menu enables some options that are specific to subsystems.
- Whether or not code and traceability information has been generated for the block or subsystem.
Note
You can also access the options in the context menu from the HDL Code tab in the Simulink Toolstrip. To access this tab, open the HDL Coder app from the Apps tab.
The following summary describes the submenu options.
| Option | Description | Availability |
|---|---|---|
| Check Subsystem Compatibility | Runs the HDL compatibility checker (checkhdl) on the subsystem. | Available only for subsystems. |
| Generate HDL for Subsystem | Runs the HDL code generator (makehdl) and generates code for the subsystem. | Available only for subsystems. |
| HDL Coder Properties | Opens the Configuration Parameters dialog box, with the top-level HDL Code Generation pane selected. | Available for blocks or subsystems. |
| HDL Block Properties | Opens a block properties dialog box for the block or subsystem. See Set and View HDL Model and Block Parameters for more information. | Available for blocks or subsystems. |
| HDL Workflow Advisor | Opens the HDL Workflow Advisor for the subsystem. | Available only for subsystems. |
| Navigate to Code | Activates the HTML code generation report window, displaying the beginning of the code generated for the selected block or subsystem. For more information, see Navigate Between Simulink Model and HDL Code by Using Traceability. | Enabled when both code and a traceability report have been generated for the block or subsystem. |
The HDL Block Properties Dialog Box
HDL Coder provides selectable alternate block implementations for many block types. Each implementation is optimized for different characteristics, such as speed or chip area. The HDL Properties dialog box lets you choose the implementation for a selected block.
Most block implementations support a number of implementation parameters that let you control further details of code generation for the block. The HDL Properties dialog box lets you set implementation parameters for a block.
The following figure shows the HDL Properties dialog box for a block.
There are a number of ways to specify implementations and implementation parameters for individual blocks or groups of blocks. See Set and View HDL Model and Block Parameters.
