Abstract:
A broadband Green's function computation technique that employs low wavenumber extraction on a modal summation is used to model the waveguide behavior of electronic components, systems, and interconnects on a printed circuit board. Use of the broadband technique permits discretizing the surface of the printed circuit board across a wide range of frequencies all at once. The broadband Green's function is also extended to via waveguides on circuit boards and power/ground plane waveguides of arbitrary shape. Such a method can analyze a given circuit board geometry over a broad frequency range several hundred times faster than is otherwise possible with existing commercial analysis tools. The present method is useful in electronic design automation for analyzing signal integrity and power integrity, reducing electromagnetic interference and ensuring electromagnetic compatibility.

Claim (Index 9):
A method, comprising:\n receiving, by a computer, a description of a geometry of a printed circuit board that includes vias and structures; determining, by the computer, broadband Green's functions for the structures; determining, by the computer, reflection coefficients from the broadband Green's functions for the structures; determining, by the computer, scattered electric fields from the reflection coefficients; determining, by the computer, electric currents on each of the vias based on the scattered electric fields; determining, by the computer, equivalent magnetic surface currents on sidewalls of the structures based on the electric currents; modifying, by the computer, the geometry of the printed circuit board based on the determined currents; and instructing, by the computer, another system to initiate design of the printed circuit board using the modified geometry.
