  • Publication number: 20220007537
    Abstract: A container module includes a baseplate assembly and a plurality of columns, where the baseplate assembly includes a base frame and a baseplate fixed on the base frame, the plurality of columns are fixed on the base frame in parallel to each other, each column has an extension section extending above the baseplate assembly, and/or a lower end of each column has an extension section extending below the baseplate assembly. A container assembly includes at least two container modules that are stacked vertically and/or connected laterally. A data center includes a function device and the container module.

  • Patent number: 9582626
    Abstract: Accurate timing analysis during STA is performed using detailed waveform information in addition to the traditional slew information. A waveform memory system efficiently stores the detailed waveforms that are used in, calculated during, and propagated throughout timing analysis for a circuit design. During the STA process, for multiple modeled stages of circuit design, a waveform including information detailing the form of the waveform is compressed, stored in, decompressed, and retrieved from a memory system. The memory system provides for storage efficiencies including long-term and short-term storage areas, multi-level storage, and separate storage for each view evaluated during the STA.

  • Patent number: 9384310
    Abstract: A system and method for performing multi-mode multi-corner (MMMC) analysis such that multiple views or conditions can be analyzed together to improve runtime by taking advantage of common steps of analysis in different corners. Views are clustered based on their similarity to one another to take advantage of calculations and other tasks that may be shared between views during timing analysis. Then, during timing analysis, each net in the design is analyzed for each view.

  • Patent number: 9003342
    Abstract: A lumped aggressor model is used to simulate multiple aggressor nets acting on a victim net. By lumping the aggressor nets together into a single input port, a single voltage excitation may be applied to the input port to simulate the model during static timing analysis. However, a record of each individual aggressor net and several associated attributes for each aggressor net is maintained such that the individual lumped aggressor nets may still be modeled as separate contributions to the attack on the victim net.

  • Patent number: 8924905
    Abstract: In one embodiment, a method of constructing an equivalent waveform model for static timing analysis of integrated circuit designs is disclosed. The method includes fitting time point coefficients (qk) and known time delay values from a delay and slew model of a receiving gate from a timing library; determining waveform values (Ikj) for input waveforms from the timing library; determining timing values (dj) from a timing table in the timing library in response to the input waveforms of the timing library; and determining coefficients (qk) by minimizing a residual of a delay equation.

  • Patent number: 8859508
    Abstract: The present invention relates to the application of 5-methyl-1,3-benzenediol or its derivatives represented by Formula I; wherein the constituent variables are as defined herein or pharmaceutical compositions thereof containing them in the preparation of medicines or functional foods. The present studies indicate that 5-methyl-1,3-benzenediol or its derivatives represented by Formula I, wherein the constituent variables are as defined herein or pharmaceutical compositions thereof containing them show more significant antidepressant effects than fluoxetine or imipramine.
