< # Enumerate set of allowed power states that can be used by a clocked object.
< # The list is kept generic to express a base minimal set.
< # State definition :-
< # Undefined: Invalid state, no power state derived information is available.
< # On: The logic block is actively running and consuming dynamic and leakage
< # energy depending on the amount of processing required.
< # Clk_gated: The clock circuity within the block is gated to save dynamic
< # energy, the power supply to the block is still on and leakage
< # energy is being consumed by the block.
< # Sram_retention: The SRAMs within the logic blocks are pulled into retention
< # state to reduce leakage energy further.
< # Off: The logic block is power gated and is not consuming any energy.
