dbCreatePath

dbCreatePath( 
d_cellView 
txl_layerPurpose
l_points 
n_width 
[ t_pathStyle ] 
) 
=> d_path / nil

Description

Creates a path.

dbCreatePath is a core database SKILL function that checks only for even multiples of database units to create a path. As a result, the created path can be off grid. To create a path with required constraints and additional level of automation use an end-application SKILL function, such as leCreatePath.

Arguments

d_cellView

The cellview.

txl_layerPurpose

Name, number, or a list of layer or layer-purpose pair.

t_purpose

Purpose, if not specified, defaults to drawing.

l_points

Point list; must contain at least two points.

n_width

Path width specified in user units.

t_pathStyle

Path style, defaults to truncateExtend.

Value Returned

d_path

The dbObject of the path.

nil

The path is not created.

Examples

dbCreatePath(cv 2 list(0:0 0:1 1:1 1:0) 4 "extendExtend")
dbCreatePath(cv list("background" "drawing") list(1:6 1:1 2:1) 2 )
dbCreatePath(cv list ("background") list(0:0 1:0 1:2 2:3) 2 "squareFlush")

If you specify a list of points where more than two points have the same X coordinate or the same Y coordinate, a message is generated in the CIW. For example, the following code generates a warning message in the CIW:

dbCreatePath(cv list("metal3" "drawing") '((2 2) (2 4) (2 6)) 2)
