摘要： Methods of using one of a plurality of configuration bitstreams in an integrated circuit are disclosed. An exemplary method comprises analyzing the plurality of implementations of a design to determine initial variations in timing among the implementations; modifying the implementations to reduce the variations in timing among the implementations; and outputting a plurality of configuration bitstreams for the implementations having variations in timing that are reduced relative to the initial variations in timing. Another method comprises generating a plurality of implementations for the design; generating a cost function for the design based upon costs (e.g., collision penalties) derived from at least two of the plurality of implementations; determining a cost for each implementation based upon the cost function; optimizing an implementation of the design by minimizing the cost of the implementation; generating a plurality of configuration bitstreams for the plurality of implementations; and outputting the plurality of configuration bitstreams.
