The copper losses (resistance and inductance) can be minimized by using wide ground and power traces or planes. If several devices are being powered from a common power source, a star-connected layout must be used. Device inputs must not be connected in series, as this will cascade the resistive losses. The position of the decoupling capacitors is important to reduce losses. Place the decoupling capacitors as close to the devices as possible. See the PCB Layout for more details.
