Abstract: Techniques for data management are described. A monotonically increasing time source that indicates an elapsed time since a reference event may be activated. Multiple snapshots of a computing object may be generated in accordance with a schedule for backing up the computing object, where the schedule may include a retention duration for retaining snapshots. Based on generating the snapshots, timestamps for the snapshots may be stored, where the timestamps may indicate respective values of the monotonically increasing time source. As part of an expiration job, a reference value of the monotonically increasing time source may be identified based on the retention duration and a current value indicated by the monotonically increasing time source. Also, a snapshot of the snapshots may be expired based on a timestamp of the snapshot corresponding to a value of the monotonically increasing time source that is less than the reference value.

Abstract: A power estimation signal selection tool identifies the signals of an IC design that should be captured in waveform data and activity formats during simulation or emulation. The power estimation signal tool reduces the volume of simulation data produced by a simulator. Signals of at least one specified type are captured in a simulated waveform data (SWD) format. Alternatively, only signals affecting “when” power conditions and abstract RTL expressions are captured in the SWD format, while all other signals are captured in a switching activity data (SAD) format. The signal selections are recorded in memory as a set of simulation directives for capturing those signals during simulation or emulation prior to power estimation. A power estimation tool can read the simulation/emulation data more efficiently and produce sufficiently accurate power estimates.
