A system expands an existing library based on simultaneous optimization of a circuit design being built and the library cells being used. The system receives a library of cells and a circuit design and performs synthesis and optimization of the circuit design. The system evaluates the circuit design to identify portions that may be candidates for new library cells. The system analyzes the library to determine whether there is an existing library cell that can be used, whether the new libcell should be added to the library, or whether the new libcell should replace an existing libcell. The system performs modeling for the new libcell to measure the improvement obtained by use of the new libcell. The system recommends the new libcell for addition to the library based on the performance modeling.
