  • Patent number: 8631381
    Abstract: The subject application relates to a method and system for power delivery network analysis. The present disclosure is directed towards a computer-implemented method for analyzing a power delivery network (PDN) associated with an electronic circuit design. Embodiments may include extracting, using at least one processor, an electromagnetic (EM) model for each of one or more discontinuity structures associated with the circuit design and generating a three dimensional adaptive mesh model that is based upon, at least in part, the extracted EM model. Numerous other features are also within the scope of the present disclosure.

  • Patent number: 8539422
    Abstract: The subject application relates to a method and system for power delivery network analysis. The present disclosure is directed towards a computer-implemented method for displaying one or more results of a power delivery network (PDN) analysis associated with an electronic circuit design. The method may include extracting, using at least one processor, an electromagnetic (EM) model for each of one or more discontinuity structures associated with the electronic circuit design. The method may further include performing a power delivery network analysis of the electronic circuit design, the PDN analysis including a Method of Moments (MoM) calculation. The method may also include displaying a three dimensional image depicting one or more results of the PDN analysis. Numerous other features are also within the scope of the present disclosure.
