Using the Bus Defaults Tab
Properties on this tab relate to aspects of a bus:
This dialog is set out to accommodate these parameters:
Line Style
From the drop down list of line styles, choose the required line for the bus. These are already defined in your Technology Line Styles.
Name Style
Choose the text style that will be used when the bus name is displayed. Choose from the list of text styles already defined in your Technology Text Styles.
Bus Terminal Offset
Bus Terminals are the short 45-degree angled segment that connect the connection to the bus. This special line is used to indicate that the connection is connected to the bus.
New bus terminals created when connecting to a bus take the Bus Terminal Offset length. You can change the default length by typing in the value that is used for both the X and Y offsets of the bus terminal. It is normal to use a value that is divisible by the same grid value as the connection. For example, if the connection is on a 50 or 100 thou grid, make the bus terminal offset 25, 50 or 100. It should be noted that this is the X,Y offset value and not the diagonal value.
Bus Terminal Direction
The direction of the Bus Terminals can be defined when they are added in the Up and Right directions for vertical and horizontal busses. The defaults used for standard Technology files are acceptable normal directions but you may choose to change these as required.
In Dialog - Apply Styles All Connected or Same Named Busses
This is used for the default value for the Apply Styles All Connected or Same Named Busses check box used in the Change Line Style dialog and the Bus Properties dialog. When you have a bus selected or in either of the dialog - Select a Bus and select Change Style, it forces all matching busses to have the same style.
