15.11.3 Creating Active Lists

You can create your own active lists. An active list can contain either macros, ports (I/Os), nets, or regions. You can use filters to determine which types of macros, ports, nets, or regions to include in your list. For example, you can create a list of all of the outgoing ports or all of the nets with a fan-out greater than six. You can also filter your list to include only instances, nets, or ports found within a specific block flow.

To create an Active List:

  1. From either the Tools or View menu, choose Active Lists > More Active Lists.
  2. In the More Active Lists dialog box, click New.
  3. In the Create Active List dialog box, use the filter to specify the types of objects you want to include in your Active List. For example, to include only unassigned instances that begin with the letters "clk," enter clk* in the Name filter, and select Unassigned in the Instances tab. These fields accept wildcards. Wildcard characters include:
    WildcardWhat It Does
    ?Matches any single character
    *Matches any string
    /This is the level-bordering symbol. “A/B” designates “object B, which is part of instance A.”
  4. Optionally, select Match case to filter on case-sensitive occurrences of a name. This limits the filter to include only text that matches the upper- and lowercase letters you enter.
  5. Enter a name for your new active list.
  6. Click OK.

The newly created Active List now appears on both the Tools and View menus.
