Using a Constraint to Manage the Length of Wires

You can manage additional length for wires that are generated by wiring synthesis. This is useful for increasing wire length in the case of u-turn wires.

Procedure

  1. Prior to running wiring synthesis, set the “Length change for Wire” constraint on the necessary objects in a design (bundle regions, bundles, harnesses or the design itself). See Overview of Rules and Constraints for more information about setting rules and constraints.

  2. Examples of using the constraint are:Length change Absolute = 5.0 for wire of signal matching Name = COND.* In this example, the Length attribute is set to 5.0 for any wires carrying signals with a Name attribute value that starts COND. Length change Offset = 4.0 for wire of signal matching Name = COND.* In this example, the Length attribute is set to the calculated graphical length plus 4.0 for any wires carrying signals with a Name attribute value that starts COND.
