21.8.8 Using Filters

You can use filters in SmartTime to limit the Path List content (that is, create a filtered list on the source and sink pin names). The filtering options appear on the top of the Timing Analysis View. You can save these filters one level below the set under which it has been created.

To use the filter:
  1. Select a set in the Domain Browser to display a given number of paths, depending on your SmartTime Options settings (100 paths by default).
  2. Enter the filter criteria in both the From and To fields and click Apply Filter. This limits the display to the paths that match your filter criteria.
