  • Power delivery network analysis
    Patent number: 9098671
    Abstract: A method and apparatus for power delivery network (PDN) analysis comprises obtaining time-domain single-pulse current response of the PDN, computing a maximum transient simultaneous switching noise (SSN) of the PDN according to the time-domain single-pulse current response, and determining that noise performance of the PDN conforms to a design requirement of the PDN if the maximum transient SSN is less than a PDN SSN threshold. Transient characteristics of the PDN can be analyzed.
    Type: Grant
    Filed: May 29, 2014
    Date of Patent: August 4, 2015
    Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
    Inventors: Tong Hao Ding, Wei Liu, Zegui Pang, Wen Yin
