  • Automatic test pattern generation (ATPG) considering crosstalk effects
    Patent number: 9218447
    Abstract: Crosstalk effects can be taken into account in automatic test pattern generation (ATPG) by providing crosstalk fault models, determining paths and/or nodes to be sensitized to activate each crosstalk fault, and optimizing to enable as many crosstalk faults as possible with a given pattern, subject to constraints. Constraints can include threshold numbers of endpoints/observation points and/or attempts to sensitize. Intermediate nodes in a crosstalk fault model path to an observation point can also be determined and/or sensitized.
    Type: Grant
    Filed: January 10, 2014
    Date of Patent: December 22, 2015
    Assignee: International Business Machines Corporation
