Renaming an Interface Port
Each interface port you place also appears as a Port object in the Ports folder under the selected design’s icon in the Project tree. The name of the port is the same as the name of the node or net to which it is connected. Node names of the form “net_n” generate during the wiring operation, but they can be renamed.
Note:
Do not use definition properties such as ID, Representation, and Owner as the names for ports.
- To rename an interface port, select it by doing one of
the following:
- Right-click its icon in the Project tree and select Edit.
- Right-click its schematic symbol and select Properties to open its Properties dialog box.
- In the Properties window, Click the port name button in the Port Name field to open the Interface Port Name dialog box. Enter the desired name (including a bus name) and click OK. The Properties window reflects the new name. Note that the port number (pnum) does not change.
- If the port is placed so that it connects to an existing node, the node is renamed to the name of the port (even if the node was manually renamed by the user). You can also change a port name attached to a node. Select the node and click the node name in its property window. A Net Name dialog box similar to the one above opens for you to specify a new name. Changing the net name changes the names of any ports attached to that node.
- If you name a port the same as an existing net, the two nodes are merged into a single node with that name. A dialog box appears for you to confirm the merge operation.
- If you delete an interface port, the node to which it was attached is renamed to a system-defined name (“net_n”).
