Abstract

An apparatus and method for managing a voltage drop on a semiconductor chip are provided. According to one exemplary embodiment of the present disclosure, a method for managing a voltage drop in a semiconductor chip may be provided. The method may include monitoring, by a voltage drop detection circuit, supply voltages of different voltage domains in a semiconductor chip, determining that a voltage drop event has occurred based on voltage information and duration information associated with the voltage drop event reported from the voltage drop detection circuit, generating diagnostic information, the diagnostic information including determining whether the voltage drop event is an external event or an internal event based on voltage information and time information reported from the voltage drop detection circuit, and taking measures based on the diagnostic information.

Description

technical field [0001] The present disclosure relates to voltage drop management for semiconductor chips, and more particularly to voltage drop management for very large scale integration (VLSI) integrated circuits (ICs) and systems on chips (SoCs). Background technique [0002] Modern system-on-chip (SoC) products rely heavily on clean and reliable power supplies to keep circuits running at high performance and integrity. Noise on power supplies, especially voltage drops, can easily cause problems ranging from single transaction errors to entire system failures. There are many factors that contribute to IR drop, and there are many mitigation techniques to address IR drop at the circuit and system levels. [0003] Voltage drops and power supply noise can be caused by external or internal events. External events include system brownouts, hot swapping, aging batteries, and voltage regulator failures. Internal events are relevant to specific applications with high load curre...
