Help for the Vergil Graph Editor

Below are some very cursory hints on using the Vergil graph editor. For more information, see the complete tutorial.

• Drag objects from the palette on the left to the graph on the right.
• External ports and relations can be created from the toolbar.
• Control-click to create new relations.
• Drag connections from one port to another. Control-drag to create a connection starting at a relation or an external port.
• Single ports are solid, Multiports are hollow.
• To broadcast a value from a single port, connect to a diamond relation.
• Right click for context menus.
• Configure external ports from Background Context Menu -> configure ports.
• Hierarchical models are outlined in red. To create a hierarchical model, drag a composite from the utilities and look inside.
• To execute, view the Run Window.

Hot Keys

The following table summarizes "hot keys," which are shortcuts for invoking frequently used commands within Vergil. All of these require holding the control key (called "Ctrl") while pushing at least one other key.

File Extensions

The following filename extensions are recognized by Vergil and opened in an appropriate editor. The "*" is a wildcard. Anything can replace it.
