Combining Pins into a Bus Pin

The Pins List allows pins to be grouped into buses, known as bus pins. To create a bus, use the following procedure:

1. In the Pins List, select the pins which will form the bus.

2. Right-click on the selection and select Combine.

3. PADS I/O Designer will ask you to enter a name for the bus pin, or you can accept the default name. Optionally, you can use the controls on this dialog to adjust the range of pins in your bus.

A bus pin is created and can be identified in the Pins List by the + at the left of the bus name.

Click + to expand or collapse the bus in the list, displaying or hiding its elements. Alternatively, select View > Expand, or View > Collapse to do the same thing. To expand or collapse all buses together, select View > Expand All, or View > Collapse All.

A bus may be split or replaced with the flat list of its elements. To split a bus right-click on it and select Split. To split all buses at once, right-click in the List Window and select Split All.

To change the name of a bus pin, right-click it in the Pins List and select Rename, or with the bus selected in the Pins List, select the menu item Edit > Rename.

You can also combine signals into bus signals, see “Combining Signals into a Bus Signal”.
