Abstract: Systems and methods of the present disclosure may provide efficient power consumption for programmable logic devices based on unused portions of programmable logic. A programmable logic device includes a plurality of programmable logic sectors that implement a circuit design, unused portions of the programmable logic device, and interconnection resources. The interconnection resources include a multiplexer that receives a control signal and that generates an output signal based on the control signal and a driver that receives the output signal and that implements a low-power mode to reduce leakage current.

Abstract: An integrated circuit includes a first voltage decrease detection circuit that has a first comparator circuit that compares a supply voltage in the integrated circuit to a threshold voltage to generate a first detection signal that indicates a decrease in the supply voltage, and a first timestamp storage circuit that stores a first timestamp in response to the first detection signal indicating the decrease. The integrated circuit includes a second voltage decrease detection circuit that has a second comparator circuit that compares the supply voltage to the threshold voltage to generate a second detection signal that indicates the decrease, and a second timestamp storage circuit that stores a second timestamp in response to the second detection signal indicating the decrease. The integrated circuit includes a control circuit that determines a location of a source of the decrease in the integrated circuit based on the first and the second timestamps.
