This section describes the Source view.
The Source view on the left contains two columns with a gray background that contain the line number and bullets that represent executable code locations. The right side of the view contains your source code.
The button with the green arrow scrolls the code browser to the location of the statement or instruction that is to be executed next. You can find this button at the top left of the Source view window.
To highlight the corresponding addresses in the disassembly view, click the left-most column in the Source view. The highlighting reveals the instructions the source statement maps to.
To set a breakpoint on the source line, double click a bullet. A filled red circle is displayed next to the line to indicate that a breakpoint has been set.
The Source view title bar has controls for:
Selecting a target line in the source using the Line: entry box.
Selecting a source file that has already been loaded using the File: drop down list.
Opening the Debug Source Files dialog box.
Right click in the Source view to display the context menu. The menu has the following options:
Insert a breakpoint at the selected location.
Enable the breakpoint at the selected location.
If a breakpoint is present on the selected instruction, selecting this option displays the Breakpoint properties dialog box.
Run to the selected instruction.
Wrap the text to fit inside the window.
Display the filename and path for the file.
The Debug Source Files dialog box lets you locate source files that are required for debugging an application. To open the dialog box, click the icon in the upper right corner of the Source view.
The tabs switch between two different views that list the properties for the source file:
This column contains a list of files that the debugged application refers to. This column is not shown in Hierarchy view.
This column shows the path for the file. The pathname comes from the debug information of the application. This path might be invalid because it refers to the original source file at compilation time. The debug pathname can be absolute or relative to the executable.
This column contains the path Model Debugger actually uses to locate the file. You can set the path by double clicking a row or selecting a row and clicking Open File. The File Open dialog box enables selecting the source file. After selecting the file, the file is opened in the debugger.
Click Find File to display the Find source file dialog box and navigate to the directory containing the source.
Click Properties to display the File Properties dialog box for the selected file. You can also use the Find File button in the File Properties dialog box to locate the file.
Model Debugger has an automatic mechanism to add replacement paths that are invoked every time you are prompted to find a source file. If the source file is found, an automatic source path replacement is calculated.
This path might not always be correct. There are situations where you must manually edit source path replacements because the automatic path is wrong for that context. You might, for example, have a header file whose name is common between two different compilers, and Model Debugger chooses the wrong one.
Click Source Paths… to open the Source Path Replacements dialog box. Use this dialog box to change the path, or priority of the paths, to the source files for the application.
Existing source file replacements are displayed in the top part of the Source Path Replacement dialog box. You can remove or reorder paths by highlighting an entry and clicking one of the following buttons:
Move the path up one position in the list.
Move the path down one position in the list.
Delete the path from the list.
Debug Path and Actual Path have the same meaning as in the Debug Source Files dialog box.
In the lower part of the Source Path Replacement dialog box, you can add new source paths or modify existing ones. The additional features are:
Provides a tree view that simplifies navigation through the debug paths in the debug information of the source file.
Click this button to select a path with a browser rather than typing in the actual path directly.
Modify the selected entry using the entered changes.
Adds the new path to the source path replacement list.
You can search for text in the active window by using the Find dialog box. Click Find on the Search menu to open the Find dialog box.
Type the text in the box and click the Find Next or Find Previous buttons to search upwards or downwards. Re-use previous search terms by clicking the drop-down arrow on the right of the text entry box.
The dialog box is modeless, so you can change views without closing it. The mode is updated automatically.
