Abstract:
A computerized schematic drawing system for creating a set of schematic configurations each containing a unique set of overlaid schematic layers, each overlaid schematic layer containing display information including schematic symbols, interconnections between schematic symbols, and other optional information, said computerized schematic drawing system comprising:a. an input mechanism for receiving:(1) the display information and modifications thereto;(2) layer assignment information specifying the overlaid schematic layer to which the display information belongs and modifications thereto;(3) configuration assignment information specifying each of the configurations to which each overlaid schematic layer belongs and modifications thereto; and(4) control information specifying other functions of the drawing system;b. a display for selectively displaying one of the configurations including the corresponding set of overlaid schematic layers; andc. processing hardware connected to said input mechanism and said display for receiving the display information, the layer assignment information, the configuration assignment information, and the control information, for storing the display information, the layer assignment information, and the configuration assignment information, for automatically propagating modifications in each of the configurations to which the overlaid schematic layer that has been modified belongs, and for causing said display to selectively display one of the configurations including the corresponding set of overlaid schematic layers.
