Abstract
An integrated circuit design tool apparatus includes a processing resource configured to support a circuit simulator, a circuit sensitivity optimizer and a circuit sensitivity calculator. The circuit sensitivity optimizer is adapted to communicate to the circuit simulator a first dynamic list of selected devices of the circuit; and a second dynamic list of selected process parameters associated with the selected devices of the first dynamic list. The circuit simulator is configured to communicate to the circuit sensitivity calculator, a performance metrics of the circuit in response thereto. The circuit sensitivity calculator is configured to determine one sensitivity coefficient for each device of the first dynamic list in response thereto. The circuit sensitivity calculator is further configured to determine and communicate to the circuit sensitivity optimizer a variance of the performance metrics and also adapted to gradually determine whether or not to further communicate with the circuit simulator.
