Abstract: Systems and methods described in this disclosure relate, generally, to analyzing electronic circuitry, and more specifically, to analyzing efficiency of clock gating in electronic circuitry. Analysis may include identifying wasted propagation of clock signals by clock gates and/or for a circuitry as a whole. In some embodiments, modified gating logic may be determined that improves clock gating efficiency, for example, by eliminating at least some wasted propagation of clock signals.

Abstract: Operating a battery management and protection system includes generating a set of events each of which has a respective frequency F/n1, F/n2 . . . F/nm, where ni are integers. One or more of the events are provided to one or more modules in the system. The events, which are generated and provided to the modules independently of a central processing unit, trigger performance of respective actions by the modules.

Abstract: A battery management and protection system can include various features to improve safety-critical and other functions. Among the features that can be included in some implementations are automatic loading of safety or other parameters during start-up of the system; a centralized timekeeper and an event system that can trigger actions in the system independently of a central processing unit; use of the same modules for both automatically-controlled safety-related measurements and firmware-controlled measurements; enhanced diagnostic features, and a sleepwalking feature that allows certain modules in the system to continue to perform various functions even when the module or the system is in a low-power sleep mode.

Abstract: A compensating DFLL (CDFLL) is disclosed that utilizes temperature readings at regular intervals in combination with production characterization data of a reference oscillator to compensate for frequency drift and nominal frequency error. In some implementations, the CDFLL selects a calibration value that is not optimal for frequency accuracy to minimize accumulated frequency error over time. More particularly, during a calibration run, mismatch between an ideal frequency and an actual frequency is measured, and the measurement is used as a starting point for a next calibration run, such that the accumulated frequency error is averaged almost to zero over time.
