Method and apparatus for extracted synthesis gate characteristics model

Method and apparatus are described for improved circuit synthesis by EDA machinery. Circuit designs are synthesized to a target hardware platform with resulting hardware characteristics correlated back to component types in the synthesis-stage circuit design. The accumulated characteristics samples then contribute to a characteristics value for the component type. The characteristics value can be used in future synthesis runs to condition processing, e.g., choosing between alternative implementation possibilities, using the characteristics value to provide an accurate prediction of a hardware implementation for the component type.
