  • Patent number: 12073160
    Abstract: Analysis of power supply noise in simulations of a design of a circuit can use per instance dynamic voltage drops (DVD) in timing analyses so that the simulated DVD values on a per victim cell basis can accurately guide the timing analysis on each victim instead of a global DVD for all victims during the timing analysis. In one embodiment, a method can: determine, during a power analysis simulation, a representation of an energy lost, during each switching window at each output of each victim cell, at one or more power supply rails of each of the victim cells in the set of victim cells due to aggressors in the design; and provide the representation of the energy lost separately for each victim cell to a timing analysis system. The representation can be a rectangle having a width defined by a switching window of a victim's output.

  • Publication number: 20230236951
    Abstract: Methods and systems are described herein for integrating model development control systems and model validation platforms. For example, the methods and systems discussed herein recite the creation and use of a model validation platform. This platform operates outside of the environment of the independently validated models as well as the native platform into which the independently validated models may be incorporated. The model validation platform may itself include a model that systematically validates other independently validated models. The model validation platform may then provide users substantive analysis of a model and its performance through one or more user interface tools such as side-by-side comparisons, recommended adjustments, and/or a plurality of adjustable model attributes for use in validating an inputted model.

  • Publication number: 20230181658
    Abstract: A method for preparing a probiotic preparation based on a W1/O/W2 double emulsion structure includes steps of: using a solution containing probiotics or a mixed solution of probiotics and a probiotic protective agent as an internal water phase W1; dissolving an emulsifier in a lipid phase O, and mixing the lipid phase O with the internal water phase W1; then preparing a primary emulsion W1/O by stirring and low-energy emulsification or high-energy emulsification; and using an emulsifier-contained solution as an external water phase W2, and adding the external water phase W2 to the primary emulsion W1/O; then preparing a W1/O/W2 double emulsion by stirring and the low-energy emulsification or the high-energy emulsification, thereby obtaining the probiotic preparation. The double emulsion system is used to embed the probiotics, which can keep the probiotics active during low-temperature storage and freezing and thawing.
