d_cellViewId

Database ID of a cellview.

txl_layerPurpose

Name, number, or a list of layers or layer-purpose pairs.

l_curvedPoints

list(boundary [l_holes])

List of one boundary and zero or more holes forming a complex closed curve. Each boundary or hole is represented by a dbClosedCurve, which is a list of vertexes. In a vertex, pairs of adjacent vertexes represent edges, which can be straight or circular:

• A straight edge is indicated by two end points without an arc qualifier on the beginning edge.
• A circular edge may be indicated by explicitly specifying the center or implicitly specifying the center. The explicit specification requires the center to be on the DBU grid. The implicit specification does not require the center to be on the DBU grid.

The points list can be a mix of explicit center-based or implicit angle-based specifications. Each element in the list describes a vertex on the curved shape.

L_curvedPoints := (elem)*

elem := {<x:float> <y:float> ([("arc" | "arcByCenter") ("cw" | "ccw")] | ["arcByAngle" <angle:float>])}

Here, keywords for explicit specification are "arc" and "arcByCenter" followed by "cw"(clockwise), or "ccw" (counter clockwise), to specify the direction. Keywords for implicit specification, where you do not define the center explicitly, are "arcCentralAngle" and "arcByAngle". In implicit specification, to specify a clockwise arc, specify a negative value for the angle specification.

x_width

Width of the curved path.

d_curvedPathId

Database ID of the curved path that is created.
