d_cache

The parasitic cache in which the filter belongs. It includes a cache_id, which is returned by parCacheFind or parCacheGet for a SKILL list that contains library, cell, and view names.

?type S_type

A valid filter type that can be R, C, L, or K. The filter only applies to parasitics of the corresponding type.

?subtype S_subtype

When S_type is set to C, indicates whether coupled or decoupled capacitance should be filtered. Valid values are coupled, decoupled, or both.

This argument is ignored for other filter types.

?members l_member_list

An ordered filter member list.

A member_list is a list of members where each member is a list in the form of (design_object_name design_object_type [ parameter_list ]).

?include S_include

Parasitics to be included. Valid values are all, none, or threshold. When set to threshold, only parasitics with a component value greater than f_threshold are included.

?threshold f_threshold

A floating point value that is ignored unless S_include is set to threshold.

?name t_name

A string that uniquely identifies the filter in the cache. If unspecified, a name is generated automatically.

?note t_note

A string note to be attached to the filter.

?verbose g_verbose

A boolean argument that controls whether a message is displayed to inform of the successful creation of a filter.

The default is t.

filter_id

The id of the new filter.

nil

The filter was not created.
