Abstract
Various embodiments include methods performed by a processor for managing voltage droop margins of a power distribution network (PDN). Various embodiments may include receiving, by a processor from a first client powered by a shared power rail within the PDN, a first requested performance corner, receiving, by the processor from a second client powered by the shared power rail, a second requested performance corner, determining by the processor a first peak current value based on the first requested performance corner, determining by the processor a second peak current value based on the second requested performance corner, determining by the processor a system voltage droop margin based on the first peak current value, the second peak current value, and an impedance value of the PDN, and adjusting a voltage of the shared power rail based on the system voltage droop margin.
