Assigning Wire / Splice / Multicore Properties by Rules

If you have added Wire, Splice or Multicore Specification constraints and Terminal Type Specification constraints to objects in a design, these rules are used during wiring synthesis to assign part properties and attributes to wires, splices and multicores that are created.

See Overview of Rules and Constraints for more information about constraints.

After you have synthesized wiring, however, you may want to change the rules and constraints relating to property/attribute specification and terminal type specification and re-apply them. You could delete all wiring and run wiring synthesis again, but it may be easier to modify the rules and constraints as required and then use the Assign Specifications by Rule dialog box to re-assign properties and attributes to wires, splices and multicores.

Procedure

1. Press Space Bar and enter Specs. The Assign Wiring Specifications by Rule Dialog Box displays.

2. Select the boxes next to the type of objects to which you want to re-assign properties and attributes.Select one of the following “Where data exists” options: Don't Overwrite Select this if you do not want to overwrite properties and attributes that are already set on objects but do want to apply the properties and attributes to objects where they are not set already.

Preserve Library Data Select this if you do not want to overwrite the properties and attributes on any wires that have library parts assigned to them but do want to overwrite the values on objects without library parts.

Overwrite and Remove Part Select this if you want to overwrite the properties and attributes on all objects and unassign library parts.

Note Select Update Prototype Wiring if you want the action to overwrite attributes and properties on wiring objects that the system synthesized with reference to prototype wiring. See Prototype Wiring for an overview of this concept. Do not select this if you want such wiring to keep attribute and property values from the prototype wiring.

3. Click the OK button to exit the dialog box and to re-assign the properties and attributes in the design.
