ANALYSIS SYSTEM FOR CONNECTION OF LOGIC CIRCUIT DIAGRAM

PURPOSE:To facilitate the analysis of connection of a logic circuit on a screen of a display by performing the analysis of the connection based on the input data received from a mouse and showing a specified connection path on the display screen with emphasis of a designated color. CONSTITUTION:An input device 1 inputs the necessary data to a logic circuit diagram. An arithmetic processor 2 applies the arithmetic processing to the input data and shows a logic circuit diagram on a display 6. A logic circuit diagram connection analyzing mechanism 4 performs the analysis of connection of the logic circuit diagram based on the input date received from a mouse 5 and specifies a connection path to output it together with the data on a designated color used for the emphasized display. Then the processor 2 shows the connection path on the screen of the display 6 with emphasis of the designated color based on the output of the mechanism 4. Therefore the connection path can be identified in a color on the circuit diagram shown on the display 6. Thus the logic circuit diagram can be easily analyzed.
