Abstract
Embodiments of a multi-level power hierarchy are described. This power hierarchy contains a higher level, which includes a first sub-circuit, and a lower level, which includes a second sub-circuit and a third sub-circuit. Moreover, the second sub-circuit and the third sub-circuit are included in branches in the power hierarchy and are separately electrically coupled to the first sub-circuit. A given sub-circuit in a given level includes programmable power protection which is configured to protect sub-circuits at higher levels of the power hierarchy from power variations associated with changes in load on branches at lower levels of the power hierarchy, thereby providing failure isolation in the power hierarchy.
