wireTaperConstraintGroup
layout wireTaperConstraintGroup string "constraintGroup_name"
Description
The taper constraint group can be used for several purposes. The primary purpose is to taper the width of a wire to match the width of the pin to which it connects. You can also adjust the widths of taper routing. Many different constraints can be included in the taper constraint group.
Another purpose is to restrict routing on the poly layer to the taper and set a taperHalo to control the length of a wire.
The default value for wireTaperConstraintGroup is virtuosoDefaultTaper. When the desired routing requires tapering, you must define the virtuosoDefaultTaper constraint group. Doing so will ensure that the correct layers and widths are being used for the tapered wires.
