US Patent 7076415 System for mixed signal synthesis

Circuit synthesis is performed utilizing an optimizer that selects design parameters for a synthesis model of a circuit based on desired performance characteristics and performance characteristics/design parameters of previously synthesized circuits. Performance characteristics and design parameters of each synthesized circuit are maintain in conjunction with the synthesis model of the circuit being synthesized. A synthesis plan identifies the synthesis model and specific instructions on how to perform optimized selection of design parameters, how to set up test benches, and how to perform the simulation.
