An improved solution for designing a circuit is provided. A set of target paths, each of which has a performance attribute that is targeted for improvement, is obtained from a design for the circuit. An influence for one or more of the nodes in the set of target paths is obtained. One or more of the nodes are selected for improvement using the influence. Subsequently, the performance attribute for each selected node is improved. For example, an implementation of the node can be replaced with an implementation having an improved performance attribute. The relative improvement provided by an alternative implementation versus a relative detriment to another performance attribute can be obtained and used in selecting the node(s) for improvement. In one embodiment, the relative improvement and influence are used to obtain a sensitivity metric for each alternative implementation, which is used in selecting the node(s) for improvement. In this manner, the circuit can be improved in a more effective manner.
