Application of optimal control theory allowed generalizing methodology of analog circuit optimization. The problem of search of minimum at times strategy of circuit optimization is formulated as a classic problem of optimization of functional of optimal control theory. A basic instrument here is a vector of control functions, allowing redistributing the expenses of processor time between the task of circuit analysis and procedure of parametric optimization. Introduced before special function, being the normalized Lyapunov function of designing process, allows finding the optimum or quasioptimum structure of vector of control functions for minimization of circuit optimization process time.
