An embodiment of a method of evaluating costs and/or benefits of possible
configurations of a manufactured product (e.g., an integrated circuit, an
electronic system, etc.) includes establishing an upgrade cost and a
redesign cost for each characteristic within a set of characteristics
associated with the product configuration. The upgrade cost is the cost
to upgrade the characteristic in a manner commensurate with other
upgraded characteristics, while the redesign cost is the cost to redesign
the product to accommodate the characteristic if it is not upgraded
commensurately. A predicted total cost and a predicted benefit for a
configuration may also be computed. In addition, the total cost for the
corresponding configuration may be subtracted from such a benefit to
determine a net benefit for the configuration. The method may be
implemented using a computer-based system including upgrade cost data and
redesign cost data.
