Before creating the P4 Resource Functions diagram, the P4 Resource Functions Taxonomy diagram should be created first.
To create a P4 Resource Functions diagram
- Either create Function Actions or drag the Functions from the Containment tree directly to the diagram pane.
 - Connect the Function Actions using the Function Edges.
 - Display the possible Resource Interactions on every Function Edge.
 
To display possible Resource Interactions, do either
-  Select Function Edge and on the smart manipulator toolbar, click 
New Resource Interaction.  - In the diagram pallet, click 
Resource Interaction and select the Function Edge.
The Realized Resource Interaction wizard opens.
