Creating busbar

Updated on November 4, 2019

The busbar has different representations for layout and schematics. In the schematics, it’s displayed as a wire, and can be attributed to some other symbol during the component creation, which is incorporated to the system in the busbar insertion. In the layout, this type of component resembles a gutter, including its stretching capabilities.
A busbar has the following features in common with a wire:

What are the similarities between the bus-type component and the wire-type component?

These features can be altered during the component’s creation. For that, it is necessary to select the option “Manually assign properties” in the component creation assistant.

• Included in the lists;
• Features displayed horizontally;
• Line color;
• Line thickness;
• Line type.

Creating a busbar…


Menu: Options > Database > New component
Ribbon: Manage > Settings > New component > New component
Command: qccadnewcomp
Component palette: Right-click on any folder > New component
Shortcut: (in the component palette) SHIFT+INS

1. Click on advance in the first window of the component creation assistant;

2. In the window that is displayed next, alter the type of component to “busbar” and name it as you wish;

3. Next, create the component’s representations, starting with schematics;

4. After selecting the rule after which it will be created, click on “New”. This will create the illustration that will serve as schematic and will be adjoined to the wire representing the busbar at the point of insertion;

5. After creating the schematic, select “Layout” from the list of representations and click on “New”;

6. Follow the previous steps to create the illustration referring to the component’s layout, just as was done with the schematic;

7. Next, define the busba characteristics, such as “Include in the list”, “automatic name” and other customised features;

8. The next window will indicate the folder in which the new component will be saved. You will conclude the creation in the window displayed after that. Busbar have the same automatic names as other components.

The busbar may be created just like rail and gutter blocks (single and multiple lines)


Every design inserted to the schematic will be adjoined to the wire that defines the busbar, but only the wire will have stretching properties.

To insert a busbar to the schematic…

These components, just like the wires, may be resized and have multiple paths inserted in the schematic

1. In the component palette, click on what is to be added;

2. Right-click on the chosen component and select the “Schematic” option under “Insert”;

3. Insert the component into the desig.

Inserting a new busbar into the layout…


Menu: Tools > Components > Insert
Ribbon: Initial > Components > Insert
Component Palette: Right-click on the component > Insert > Layout

The busbar’s behaviour on the layout is similar to that of gutters. It is possible to resize it during the insertion using the attribute “QC_PARAM_LENGTH”. It can be done through the following steps:

1. In the component palette, click on what is to be added;

2. Right-click on the chosen component and select “Layout” under “Insert”;

3. Add the component to the design.

Managing busbar addressing…


Menu: Tools > Wires > Address
Ribbon: Initial > Wires > Address

1. Click on the “Address” option;

2. The busbar should be addressed in the same way as the wires;

Both allow for repetition in relationships between components. In the listings, the they will be mentioned in a similar way as other components.
