Abstract: Various implementations described herein are directed to a method that acquires operating frequencies for a first set of ring oscillators disposed in a first integrated circuit, determines one or more first coefficients and a first constant for each ring oscillator in the first set, and determines a correlation between each of the first coefficients and the first constant. Also, the method may acquire a single operating frequency for each of a second set of ring oscillators in a second integrated circuit at a single pre-determined temperature so as to determine a second constant, predict one or more second coefficients for each ring oscillator in the second set based on the second constant and the correlation, and derive a temperature dependence based on the single operating frequency using the one or more second coefficients and the second constant for each of the second set of ring oscillators.

Abstract: Various implementations described herein are related to a device having level shifter circuitry configured to receive isolation control signals in a first voltage domain and provide an output signal in a second voltage domain that is different than the first voltage domain. The device may include isolation logic circuitry configured to receive a data input signal in the first voltage domain and then provide the isolation control signals to the level shifter circuitry in the first voltage domain based on the data input signal. The isolation logic circuitry may include control passgates that enable the data input signal to propagate to the level shifter circuitry via the isolation control signals.

Abstract: According to one implementation of the present disclosure, a method of profiling the temperature and voltage across different locations within a processor is disclosed. The method includes: in a first stage, determining respective first and second voltage sensitivity coefficients and respective first and second temperature sensitivity coefficients corresponding to a pair of ring oscillators; and in a second stage, determining a voltage deviation and a temperature deviation from a predetermined reference voltage and a predetermined reference temperature respectively, based on the determined respective first and second voltage sensitivity coefficients and the determined respective first and second temperature sensitivity coefficients.
