Abstract: Systems and methods for power sequencing include, for an integrated circuit comprising one or more logic instances, one or more power multiplexers to select from at least a first power rail and a second power rail, an active power rail to supply power to the one or more logic instances. One or more sequence multiplexers are used to choose from at least a first power sequence for the first power rail and a second power sequence for the second power rail, an active power sequence. One or more head switches coupled to the one or more logic instances are either turned on, in the active power sequence, to supply power to the one or more logic instances from the active power rail, or turned off, in the active power sequence, the one or more head switches, to power down the one or more logic instances.
