PURPOSE:To exactly select a desired layer by providing a means to table each layer information and to display the information on a display screen, a means to select the layer information in the table on this screen and a means to draw the wiring pattern of the layer corresponding to the layer information. CONSTITUTION:The display system is constituted with an input / output device 1, arithmetic processing unit 2, data storage device 3 and design layer selection mechanism 4. Especially, the design layer selection mechanism 4 is equipped with a means 5 to table the respective layer information such as the layer number of each layer in a printed circuit board and a wiring direction, and to display the information on the display screen, a means 6 to select the layer information of the desired layer in the table on this display screen, a means to emphasize and display a column for the layer information of this selected layer and a means 7 to draw the wiring pattern of the layer corresponding to these emphasized and displayed layer information. Thus, since the layer can be selected while confirming layer constitution information on the display screen, operability can be improved when interactive processing such as the addition and deletion of the pattern is executed. |
