dbCreateRailDefByAttr(
d_cvId
t_name
l_attr_dpl
) 
=> d_railDefId / nil

Description

Creates railDef based on the SKILL DPL of the railDef object specification. Contents of the SKILL DPL specification are checked before railDef is created.

Arguments

d_cvId	Database ID of a cellview.
t_name	Name of a railDef.
l_attr_dpl	SKILL DPL of the railDef specification. DPL is a list of following required and optional attributes: Required pwrRail = list(nil) pwrRail->lpp = '("Metal1" "drawing") pwrRail->netName = "VDD!" pwrRail->width = 0.064 pwrRail->refOnArea = "bottomAlignment" pwrRail->refOnRail = "bottomAlignment" Optional pwrRail->railFigType = "pathSeg“ pwrRail->offset pwrRail->beginOffset pwrRail->endOffset

Value Returned

d_railDeff	Database ID of railDef that is created.
nil	Returned in case of failure.

Examples

Creates a SKILL DPL for railDef specification and creates railDef based on the SKILL DPL.

;Creating SKILL DPL for railDef specification

         gndRail = list(nil)

         gndRail->lpp = list("gndLayer" "drawing")

         gndRail->width = 0.02

         gndRail->refOnArea = "topAlignment"

         gndRail->refOnRail = "centerAlignment"

         gndRail->netName = "gndNet"

         gndRail->railFigType = "pathSeg"

;; Creating railDef

         rdef = dbCreateRailDefByAttr(cv "railDef" gndRail)
