A method for controlling powering of a mobile platform comprising a first Finite State Machine (FSM) and a second FSM. The method comprises synchronizing the first FSM with the second FSM, wherein the first FSM is arranged on a first Integrated Circuit (IC) comprised in the mobile platform and configured to control a first Power Management Unit (PMU) arranged on the first IC, and wherein the second FSM is arranged on a second IC comprised in the mobile platform and configured to control a second PMU arranged on the second IC, whereby the first PMU and the second PMU are synchronized to operate simultaneously during rank-up and rank-down, thereby providing power control of the mobile platform.
