Abstract: The size and the complexity of the systems grow constantly. One of the main problems of a large system design is the excessive computer time that is necessary to achieve the final point of the design process. There are some powerful methods that reduce necessary time for network analysis. The progress in optimization technique favors the development of fast algorithms for electronic networks design too. Nevertheless, the time of a large-scale circuit analysis and the time of any optimization procedure increase when the network scale increases. Meanwhile, it is possible to reformulate the total network design problem to generalize design process. The general design methodology was formulated on basis of the optimal control theory approach that includes a special control vector. The problem of time-optimal network design strategy is formulated as the typical problem for some functional minimization of the control theory. The design process in this case is formulated as the controllable dynamic system. The behavior of the Lyapunov function of this dynamic system and the properties of its time derivative have sufficient information to select more perspective design strategies from infinite set of the different design strategies. The special function can be proposed to predict a structure of the time optimal design strategy. This function is a key to construct the optimal behavior of the control vector. The solution of this problem gives possibility to construct the minimal-time system design algorithm.
