Adding 3D Information in Ultiboard
Excluding a Component from Annotation
Some components in schematic capture (Multisim) have no meaning from a layout perspective, for example, components that are simulating an external power supply. You can prevent a component in schematic capture from transferring to layout (Ultiboard) by ensuring that the component has no footprint. The same is possible from the layout perspective, for example, mounting holes would not have meaning in schematic capture, but how do you prevent it from back annotating to Multisim or being detected as removed in a forward annotation?
Introducing the new "DONOTANNOTATE" attribute. That's right, as of version 11.0, it is possible to mark parts in Ultiboard as not for annotation. Parts with this attribute are not included in the annotation file when back annotating to Multisim, and they are ignored when generating a list of differences during forward annotation. Follow the steps below to modify an exiting part to add this attribute.
- Select the part you want to modify, then click Edit > Properties and select the Attributes tab
- Click the New button, then select Comment in the Select Layer for Attribute dialog, and click OK (any layer will be okay)
- Input or select DONOTANNOTATE for the Tag
- Input 1 for the Value
- Select Invisible for Visibility
- Click OK
Lastly, don't forget that this attribute can be saved to the database when editing a part in Ultiboard. So if you are creating a custom part, make sure you think about whether the part should be annotated to Ultiboard.
