Cosimulation Wizard

Generate a cosimulation block or System object from existing HDL files

Description

Run your HDL design as part of a Simulink^® model or MATLAB^® script. The Cosimulation Wizard generates a cosimulation block, System object™, or MATLAB callback function. In addition, the wizard creates MATLAB scripts that can compile the HDL and start the HDL simulator.

Open the Cosimulation Wizard App

• Simulink Toolstrip: In the Apps tab, under Verification, Validation and Test, click the HDL Verifier icon to open the HDL Verifier tab. Then, select HDL Cosimulation in the Mode section, and click Import HDL Files.

• MATLAB command prompt: Enter cosimWizard.

Examples

Generate and Edit Parameter File

1. In the Simulation Options pane, specify a filename in the Parameter file field.

   

2. Click Generate. A new parameter file is created, with default parameter values.

3. Click Edit.

4. In the file that opens, uncomment the lines with the parameters you want to override, and then set their values. For example, set coeff1 to 0 and coeff2 to 18.

   

5. Save the file, and click Next.

Use Existing Parameter File

If you know the parameters in your design hierarchy and you have specific settings for the parameters you want to use, you can write your own parameter file.

1. In the Simulation Options pane, specify the filename in the Parameter file parameter.

2. You can optionally change parameter values. To do so click Edit, and set the parameters to the new values.

3. Click Next.
