Debugging an HLS component is only possible after, or as part of C simulation. The following figure shows the Debug view for an HLS component. You can view the values of variables and expressions directly in the Debug view. In the Variables view, you can edit the values of variables to force the variable to a specific state for instance. In the Watch view, you can monitor the value of expressions. Use the '+' command in the Watch view to add an expression to watch. Refer to Debug View for additional details on the available features and views.
