ABSTRACT:
A schematic diagram generator processes a netlist to generate a schematic diagram based on a set of placement rules, corresponding to a separate characteristic pattern of interconnected devices and specifying a constraint on relative placement within the schematic diagram of symbols representing devices forming the pattern. The generator identifies each set of devices in the netlist that exhibits any rule's interconnection pattern as a separate “soft group”, places a constraint consistent with the rule on relative positioning within the schematic diagram of symbols representing the soft group, resolves any constraint conflicts in accordance with a constraint resolution scheme, and then places all device symbols in the schematic diagram in a manner consistent accordance with the constraints.
