Abstract
PURPOSE: To restore a logic circuit diagram easy to be recognized by a designer, by enabling a data signal system and a control signal system to be recognized, and performing separated wiring by distinguishing both systems so as to recognize their wiring separately.
CONSTITUTION: Inverters 9 and 10 are selected based on the connection information of the logic circuit diagram. Next, transmission gates (5W7) to which the output terminals of the inverters 9 and 10 are connected are selected. The inverters 9 and 10 are not wired directly with the data signal system consisting of transmission gates (5W8) other than the gates connected to the inverters 9 and 10, and another circuit device, and the wiring is shown by a coupler, and also, a logic circuit where they are arranged separately in separated positions can be obtained. Since the gates 5W8 are controlled so that they are energized when an input clock pulse CK is set at an L level, and are de- energized when the CK is set at an H level, the inverters 9 and 10 constitute the control signal system. Since the control signal system is arranged separately from the data signal system, the logic circuit diagram easy to be recognized can be obtained.
