OPTOMEGA: an environment for analog circuit optimization

The development of OPTOMEGA, an environment of analog circuit optimization, is presented. OPTOMEGA communicates with the electric circuit simulator OMEGA and the Matlab engine by the Interprocess Communications (IPC) techniques. We have used the Matlab engine as a subenvironment for pre-developing functions and methods and a post-processing tool in order to map the circuit responses on desirable performances. OPTOMEGA consists of the nominal circuit optimization by global optimization algorithms and the parametric yield or Average Quality Index (AQI) optimization. The tool includes efficient Monte Carlo analysis algorithms which ensure an extensive verification and characterization of the design. Two circuit optimization examples are given
