Abstract: In this paper, the mathematical model of the CMOS inverter chain for multiple-criterion optimization and the procedure of building objective functions are given. An algorithm of asynchronous statistical optimization is suggested in which objective functions of yield and others are optimized with different steps. The analytic descriptions of calculating the circuit yield can be obtained. At last, an example of the CMOS design with multiple objectives is given with numerical analysis, and the feasibility of the algorithm is demonstrated based on the simulation results.
