A design structure for eliminating step response power supply perturbation during voltage island power-uppower-down on an integrated circuit is disclosed. The CAD model, which is representative of the surface of the physical part, and the sensor model, which is representative of a 3-D image capturing sensor, are both input into a sensor planner. However, harmful processes arise from the interactions between the atoms and the nearby surface. Processes identified with a process markup tag associating said processes with said user preference are executed and the order of processes is dependent on the user preference. A three-dimensional map is constructed based on the \u0394R2 map.
