Assign Net Class

You can classify nets according to their electrical characteristics. By using net class assigned to each net, DDR nets are automatically grouped when performing Automatic DDR Bus Analysis.

From the menu bar, click Properties > Net Classes. The Net Classes dialog opens showing a default net class and string filter.

You can save and re-load net class files by clicking Import or Export. You can edit current net class items by clicking EDIT. You can add a new net class item by clicking Add.

Upon clicking Add, the ADD dialog opens. You can assign new net class name and search strings. Two operators are used in the search string: # and *.
  • *: Any string
  • #: One Number

This net class definition will be used in the Properties > Nets menu to assign net class to each net. By using net class assigned to each net, DDR nets are automatically grouped when performing Automatic DDR Bus Analysis.
