VectorCAST version 2019 supports the capability to display and graphically visualize control flow and code coverage. This feature can be accessed by enabling Control Flow from within the Custom Tools menu.

The Control Flow Graph works from within both the Cover and Unit Test Environmets, it uses the context from within the unit/subprogram hierarchy (Unit Test) or file-level (Cover).
Depending on which level in the environment is selected, a pull down menu shows up with the routines and units.

When you select an item from this list, it then displays the graph inside of the MDI.
In the Unit Test tool:
Control Flow Graphs are generated as SVG (scalable vector graphics), the MDI displays these like a HTML document.
If the graph is not of ideal size, zoom is enabled, normal MDI behavior. These files can also be exported or saved for future references and are able to be embedded inside of reports.
