Megafunctions List

Displays a list of Pin Planner"“ compatible megafunctions that you created or imported into the design.

Megafunction Table

• Megafunction—Displays the name of the megafunction.
• Instance—Displays the name you assigned to the megafunction instance.
• Port Name—Displays the names of the ports contained in the megafunction. Buses are displayed as a group.
• Direction—Displays whether the port is an input, output, or bidirectional port.
• Type—Specifies whether the port is internal or external. Nodes assigned to internal ports cannot be assigned to device pins. If you change the port type, all ports connected by the same node are changed likewise. Nodes assigned to internal ports are not displayed in the Groups and All Pins lists, but do appear in the generated top-level design file as virtual pins. If you change all the ports in a megafunction group to internal ports, they do not display in the Groups list. Nodes assigned to external ports are assigned to device pins.
• Node Name—Displays the node name associated with the port. You can change the node name to connect multiple ports in different groups to a single node.
