The computation time required for the analysis of a complete circuit can be too long for an adequat use of optimization methods in industrial circuit design.
The application of symbolic analysis together with model order reduction techniques can reduce the computational cost and hence make optimization a more suitable tool for the circuit designer. To evaluate the possibilities offered by this technique, a linear test case has been considered: the problem of an inductor simulation has been analyzed by introducing simplified analytical expressions and different optimization algorithms in the fitting/optimization process. Then the technique has been applied to a real circuit, a voltage reference, trying to improve the stability of the reference over the temperature.
