Experimental results are presented to demonstrate the usefulness of this approach. For a set of randomly selected benchmark circuits, on the average, 30%-50% of wires have alternative wires.  ...  Allowing the logic blocks to have alternative functions also increases the flexibility of routing. The redundancy addition and removal techniques are used to identify such alternative wires.  ...  For an external target wire, we can obtain a set of multiple-wire alternatives using the approach described earlier. In the following, we discuss the cost of an alternative wire.  ...
