An integrated circuit (IC) is disclosed herein for adaptive power multiplexing with a power distribution network. In an example aspect, the integrated circuit includes a first power rail, a second power rail, and a load power rail. The integrated circuit also includes multiple power-multiplexer tiles and power-multiplexer control circuitry. The multiple power-multiplexer tiles are coupled in series in a chained arrangement and configured to jointly perform a power-multiplexing operation. Each power-multiplexer tile is configured to switch between coupling the load power rail to the first power rail and coupling the load power rail to the second power rail. The power-multiplexer control circuitry is configured to control a direction of current flow to prevent cross-conduction between the first power rail and the second power rail during the power-multiplexing operation.

Adaptive power multiplexing with a power distribution network

A series of current repeaters with localized feedback is provided. Each current that precedes a subsequent current repeater in the series is configured to receive a feedback current from the subsequent current repeater and generate an error signal accordingly with a differential amplifier so as to reduce current repetition errors that would otherwise result from an offset voltage in the differential amplifier.

A computing device for indicating a physical layer error is described. The computing device includes a processor and instructions stored in memory that is in electronic communication with the processor. The computing device generates a command for a testing device. The command includes a directive to capture at least one physical layer signal corresponding to a communications interface between a first electronic device and a second electronic device. The computing device also obtains data representing the at least one physical layer signal. The computing device additionally stores the data in a storage device to obtain stored data. The stored data indicates any physical layer error.
