Low-power designs that use power shutoff (PSO) and multiple-supply voltage (MSV) will have circuits that operate at various voltages, including no voltage. To describe the combination of allowable voltages in a design, CPF uses power mode, and UPF 1.0 uses power state.
In CPF, each power mode represents one combination of the states of all power domains. In UPF 1.0, each power ... » read more
