Naming Scheme

Naming Scheme - You can use pre-defined naming scheme by selecting a predefined Naming Scheme from the drop down list. Or you define your own Naming Scheme using valid keywords. You can select any combination of valid keywords in any order to define your own Naming Scheme. You can use any non-alphanumeric character in your Naming Scheme to separate keywords e.g. _ * . @ etc Choose from the keywords tabulated below:

Keyword	Definition
$RoomName	Name of the associated Room, as determined by the style chosen in the Room Name Options
$ComponentPrefix	Component Logical Designator prefix (e.g. U for U1)
$ComponentIndex	Component Logical Designator index (e.g. 1 for U1)
$ChannelPrefix	Logical Sheet Symbol Designator
$ChannelIndex	Index you have specified to distinguish between different channels
$ChannelAlpha	Channel Index expressed as an alpha character. This format is only useful if your design contains less than 26 channels in total, or if you are using a hierarchical designator format
$SheetDesignator	Designator assigned to the Sheet Symbol
$SheetNumber	The Sheet Number assigned to the Sheet. If Compiled Sheets have been annotated, this information will be used
$DocumentNumber	The Document Number specified in Document Options
$GlobalIndex	User defined index. You can specify the order, Start Index and/or a suffix in the Global Index Options for each schematic document. These options are displayed in the Board Level Annotation Options dialog. Global Index is calculated for all undesignated components. If you add new components after you have performed a Board Level Annotation, these components will be annotated with a new Global Index and the existing components will retain their Global Index. To recalculate the Global Index for all components, Reset All first.

Room Name Options

Room Naming Style - Use the Room Naming Style drop-down list to define the naming format you require for the rooms in your design. These rooms are created by default when you update the project schematics to the PCB. There are five styles available - two flat and three hierarchical.

Flat room name formats	Hierarchical room name formats
Flat Numeric with Names	Numeric Name Path
Flat Alpha with Names	Alpha Name Path
	Mixed Name Path

Level Separator for Paths - Specify the required character/symbol for separating the path information when using the hierarchical naming styles. There are no restrictions on the character used for the Level Separator; however, a single non-alphanumeric character is easier to read.
