Filed:

Apr 6, 2021

Appl. No.:

17/223583

Inventors:

- Singapore, SG
Bharath UPPUTURI - Santa Clara CA, US
Bruce KAUFFMAN - Santa Clara CA, US
Novinder WARAICH - Union City CA, US
Paul SEBATA - Fremont CA, US

International Classification:

G06F 1/324
G06F 1/3296
G06F 1/30
G06F 1/08

Abstract:

A system includes a controller configured to receive a signal indicating whether a droop event has occurred. The system also includes a plurality of delay elements where each delay element of the plurality of delay elements responsive to a signal from the controller receives an input signal and outputs an output signal that is a delayed version of the input signal. At least one delay element of the plurality of delay elements receives a clocking signal as its input signal. The system also includes a selector configured to select rising edges and falling edges of output signals from the plurality of delay elements to form a modified clocking signal. The modified clocking signal is a modified version of the clocking signal.

Paul Sebata - Santa Clara CA, US

International Classification:

G01R 25/00
G01R 31/30

Abstract:

A system includes a plurality of delay elements configured to receive an input clock signal. The system further includes an edge transition detector coupled to the plurality of delay elements. The plurality of delay elements is configured to detect the input clock signal transitioning from one value to another value. The system also includes a circuitry configured to determine a number of delay elements of the plurality of delay elements that the input clock signal propagates through prior to the input clock signal transitioning. The system also includes a logic or controller configured to determine whether a droop event has occurred based on the number of delay elements.
