Auto-Wire to Bus

You can use the auto-wiring feature to connect the pins on a part to a bus. You can also connect pins and wires from across the page to a single bus.
In this feature, you simply need to select the pins (and wires) to connect to the bus, choose the Connect to Bus command and finally provide a net alias and all the connections to the bus are made.

To connect Part Pins and / or wires to a Bus

1. From the Place menu, choose Auto Wire then choose Connect to Bus.
   Or click the Auto Connect to Bus button on the Draw toolbar.
   Capture is now in the Auto-Wire mode. Notice the cursor changes to the Auto-Wire cursor.

2. Select any number of pins and / or wires to be connected to the bus.

   Since you are in the Connect to Bus mode, you do not need to press the Ctrl key to multi-select points on the page.

3. Select the bus.

   As soon as you select the bus, the wire connections between the selected points on the page and the bus are created. Notice that the bus entries for these connections are also mad

   
   When all the connections to the bus are made, you are prompted for the net alias.
   This net alias will be used for all the connections to the bus. So you need to provide a alias name prefix followed by a numeric range in square brackets. So that each net alias in the connections will use name prefix followed by the sequenced numeric.
   Take the example of the following alias name prefix and number range:
   AD [9-0]
   The net aliases will be named AD9, AD8, AD7 through to AD0.

   If you the numeric range that you provide is greater than the number of objects to be connected to the bus, Capture will discard the un-necessary number values.

4. Enter the net alias name prefix followed by the numeric range.
   All the connections to the bus are complete along with the number sequenced net aliases.

The auto-connect to bus feature is extremely sensitive to the exact location of the mouse click on the objects (wires or pins) on the schematic. When you use the feature to connect wires to a bus, you need to ensure that you click at the precise end of the wires. Alternatively, when using this feature, you will find it easier to connect the bus directly to the pins on the part.
