Bus Vector Connect

The Bus Vector Connect function is the preferred method for placing numerous connections from a multi-pinned device, such as an IC, to a bus.

The following example details the connection of an IC to a bus. However, you can use Bus Vector Connect to connect any multi-pin device to a bus.

Complete the following steps to connect a device to a bus:

1. Place the component that you wish to connect to the bus on the workspace.
2. Place a bus on the workspace.

   For best results, position the bus so that it is at right-angles to the pins to be connected. The bus should be long enough to accomodate the number of connections, as in the example in the above figure.

   

3. Click once on the component to select it and select Place»Bus vector connect to display the Bus Vector Connect dialog box.
4. In the Component box, select the side of the component from which pins will be connected from the Pins drop-down list. The list below the Pins field is populated based on your selection.
5. Highlight the pins that you wish to attach to the bus, as in the example below.

   

6. Click on the activated down-arrow button to move the selected pins to the bottom left field.

   

     If you move an incorrect item, highlight it and click on the up-arrow button to return it to the Pins list.

7. In the Bus box, select the bus you wish to connect to from the Name drop-down list.

   

8. In the Bus lines field, select the bus lines you wish to use and click on the enabled down-arrow button to move the selection to the lower-right field.

   

     If the Bus lines field is empty, you can click on the Auto-assign button to automatically create and assign bus line names that correspond to the pin names. You can also add new bus lines by clicking Add bus lines.

9. Click OK.

   The connections to the bus are made as in the example in the figure below.
