The Board Level Annotation Options dialog provides controls to further customize annotation using either predefined or custom naming schemes.

For more information about annotation, refer to the Annotating the Components page.


The dialog is accessed from the schematic editor by clicking the Annotate Options button in the Board Level Annotate dialog


Name Scheme

  • Naming Scheme - use the drop-down to select a predefined naming scheme or define your own naming scheme using valid keywords. You can select any combination of valid keywords in any order and any non-alphanumeric characters to separate keywords. Choose from the keywords tabulated below:




Name of the associated Room as determined by the style chosen in the Room Name Options.


Component Logical Designator prefix (e.g., U for U1).


Component Logical Designator index (e.g., 1 for U1).


Logical Sheet Symbol Designator.


Index you have specified to distinguish between different channels.


Channel Index expressed as an alpha character. This format is useful only if your design contains less than 26 channels in total, or if you are using a hierarchical designator format.


Designator assigned to the Sheet Symbol.


The Sheet Number assigned to the Sheet. If Compiled Sheets have been annotated, this information will be used.


The Document Number specified in Document Options.


User defined index. You can specify the order, Start Index and/or a suffix in the Global Index Options for each schematic document. Global Index is calculated for all non-designated 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. 

The following options and controls will vary depending on the document being annotated.
