Patent number: 11768237Abstract: This document describes techniques and systems for leakage screening based on power prediction. In particular, the described systems and techniques estimate, during a silicon manufacturing process, use-case power (e.g., low power, ambient power, high power, gaming power) to apply leakage screening for apart (e.g., a chip package). In some aspects, measurable silicon parameters (e.g., leakage values, bin values, processor sensor values) may be used for use-case power prediction. Using the described techniques, a maximum allowable predicted use-case power can be determined and used for leakage screening regardless of an individual rail leakage or voltage bin assignment.Type: GrantFiled: May 12, 2022Date of Patent: September 26, 2023Assignee: Google LLCInventors: Emre Tuncer, Kaushik Balamukundhan, Yiran Li

Publication number: 20230131119Abstract: Detecting voltage-based attacks on an integrated circuit (IC) is difficult in the presence of clock jitter. Propagating signals can exhibit a total delay that is due to a delay component resulting from a voltage-based attack and a delay characteristic resulting from clock fluctuation. Voltage-variation detection circuitry includes first and second voltage-dependent circuits and a voltage analysis circuit. The voltage-dependent circuits produce first and second signals that are indicative of a voltage level responsive to a clock signal and based on different first and second voltage sensitivities. The voltage analysis circuit generates a voltage alert signal based on the first and second signals. A combined signal neutralizes the delay characteristic in the first and second signals, but the delay component due to the voltage variation can be at least partially maintained. Thus, a voltage-based attack is detectable in the presence of clock fluctuation by using two voltage-dependent circuits.Type: ApplicationFiled: October 31, 2022Publication date: April 27, 2023Applicant: Google LLCInventors: Emre Tuncer, Huachang Xu, Ramprasad Raghavan, Fanny Gur, Manish Harnur
