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.
