The opportunities created by modern microelectronic technology cannot be effectively exploited, because of weaknesses of the traditional circuit synthesis methods used in today's CAD tools. In this paper, a new information-driven circuit synthesis method is discussed. It differs considerably from all other known methods. It is based on our original information-driven approach to circuit synthesis, bottom-up general functional decomposition and theory of information relationship measures. A special focus of the paper is on the role and usage of information trans-coders in the information-driven circuit synthesis. The experimental results from the automatic circuit synthesis tool that implements the method demonstrate that the information-driven general decomposition produces very fast and compact gate-based circuits, and the information trans-coders play an important role in achieving this aim.
