Methods and apparatuses generate a split power plane for a multiplayer
printed circuit board (PCB). An aspect of the invention supports the
generation of a split power plane by constructing wireframes
corresponding to each of the power voltages. If a crossover between
different voltage wireframes exists, at least one of the voltage
wireframes may be modified in order to eliminate the crossover. With
another aspect of the invention, a trace layout, corresponding to the
wireframe, is constructed in accordance with electrical current
requirements, e.g. average electrical current and peak electrical
current, of the associated components. With another aspect of the
invention, a plane that contain the traces that associated with a power
voltage may be enhanced by increasing the associated area of the layout
in accordance with the available area of the split power plane. The
enhancement of a plane may be prioritized in accordance with peak
electrical current that is associated with the plane.
