Setting DFM Analysis Preferences for PADS Layout

Use the DFM Analysis wizard to specify the units of measure in which to view results, to edit default constraints used to set violation thresholds, and to construct rules for assigning attributes to features of the design during translation.

The next time you open the DFM Analysis wizard, options display as you set them. The constraint values list should display in the units of measure you chose, and the measurements in the Result Viewer should also display in the units you chose. See “DFMA Result Viewer”.

Procedure

  1. In your PADS Layout application, select Tools > DFM Analyses > Setup.

    The DFM Analysis wizard opens:



  2. In Specify display units? select Imperial or Metric.

    This controls the units in which to display constraint values in the wizard, and analysis measurements in the Result Viewer. See “DFMA Result Viewer”.

  3. To view or modify the constraints, set Preview analysis constraints = Yes, and click the Open Constraints Editor bar. See “Modifying Analysis Constraints”.
  4. To create attribute rules, set Assign feature attributes by rules = Yes, and click the Open Attribute Assignment Editor bar. See “Creating Feature Attribute Rules”.
  5. Click Next.

    A message box opens stating that your setup values have been saved.

  6. Click Next again to exit the application.
