Responding to a single command, a layout versus schematic (LVS) tool
processes layout data describing positions of conductors on layers of an
IC to produce data representing a shape recognition layer depicting
boundary shapes of spirals of drawn inductors. The boundary shape of a
spiral is the shape of the spiral as viewed from above with all of the
layers of conductive material forming the spiral superimposed. The LVS
tool then processes the shape recognition layer data to identify the type
and position of each drawn inductor, to determine whether each inductor's
spiral turns are of uniform width and spacing, to detect connectivity
violations, and to determine parameters relating to the shape of the
spiral from which its inductance can be computed.
