  • Method, apparatus and computer program product for implementing automated detection excess aggressor shape capacitance coupling in printed circuit board layouts
    Publication number: 20050125752
    Abstract: A method, apparatus and computer program product are provided for implementing automated detection of excess aggressor shape capacitance coupling in printed circuit board layouts. A PCB design file containing an electronic representation of a printed circuit board design is received. A list of candidate shapes is identified. The candidate shapes are disposed on layers adjacent to aggressor planes. A capacitance coupling the candidate shapes to adjacent aggressor planes is calculated. A ratio of the calculated capacitance and a decoupling capacitance connecting the candidate shapes to a reference plane is determined.
