  • Publication number: 20240143878
    Abstract: A method of performing static timing analysis for a circuit design includes, in part, identifying a multitude of logic blocks of the circuit design matching a design pattern; determining values of a multitude of electrical properties associated with a first logic block representative of each of the plurality of logic blocks; and determining, during the static timing analysis, a delay associated with each of the multitude of logic blocks using the values of the electrical properties.

  • Publication number: 20220398369
    Abstract: Disclosed is a method and apparatus that determines receiver capacitance values for a receiver cell from a multi-segment receiver capacitance model (C1Cn) model. Values for receiver capacitance are determined from a Composite Current Source for Noise (CCSN) model under conditions used to attain receiver capacitance values for the C1Cn model Difference values for the difference between the values from the CCSN model and from the C1Cn model are determined. Calibration factors are iteratively applied to parameters of the CCSN model to obtain a minimum difference value for difference between receiver capacitance values from the CCSN model and receiver capacitance values from the C1Cn model. Calibration factor values that result in the difference value being within an acceptable range are stored.
