1. A machine-implemented method for debugging a low-level process associated with a graphical notation diagram comprising: setting one or more high-level debug events on one or more graphical elements in the graphical notation diagram; initiating a debug mode, wherein initiating the debug mode includes evaluating the one or more graphical elements in the diagram to identify the one or more high-level debug events; and generating a set of pending event requests, wherein the set of pending event requests is generated by creating an event request for each of the one or more high-level debug events.
