Description

Sets the default state for specified layers in the configuration file for the Filters tab of the DRD Options form. If the function is run without a maskLayout cellview open, the settings are discarded.

You can save settings from the DRD Options form to a configuration file or, conversely, load the settings from the configuration file to the form. For more information, see DRD Configuration File in Virtuoso Design Rule Driven Editing User Guide.

Virtuoso does not consider this function if specified in .cdsinit or .cdsenv.
