Abstract: The subject technology receives a query, the query including a statement for performing the query. The subject technology performs a first lookup operation on a multi-phase cache based on the query. The subject technology performs, in response to a first cache miss of the multi-phase cache, parsing of the statement from the query. The subject technology performs, based on the parsing, a compilation process on the query to generate a compiled query plan, the compilation process determining an optimization and a generalization for the query. The subject technology determines that the compiled query plan is cacheable. The subject technology registers, in response to the compiled query plan being cacheable, a dummy entry in the multi-phase cache.

Abstract: Introduced herein is a technique that reliably measures on-die noise of logic in a chip. The introduced technique places a noise measurement system in partitions of the chip that are expected to cause the most noise. The introduced technique utilizes a continuous free-running clock that feeds functional frequency to the noise measurement circuit throughout the noise measurement scan test. This allows the noise measurement circuit to measure the voltage noise of the logic during a shift phase, which was not possible in the conventional noise measurement method. Also, by being able to measure the voltage noise during a shift phase and hence in both phases of the scan test, the introduced technique can perform a more comprehensive noise measurement not only during ATE testing but as part of IST in the field.

Abstract: The protection cap is a silicone cap that has Velcro pieces on the inside to allow for attachment on a sliding mitt. Once attached, it helps protect the hand and fingers further when sliding.
