Abstract:
A method of modeling inductive effects in an integrated circuit/system that comprises a plurality of conductors, the method comprising:defining a plurality of windows, respective ones of the plurality of windows being associated with respective ones of the plurality of conductors and having other ones of the plurality of conductors contained therein: and forming a plurality of localized susceptive coupling vectors, respective ones of the plurality of localized susceptive coupling vectors being populated with susceptive coupling elements by determining respective currents flowing through the other ones of the plurality of conductors such that the respective ones of the plurality of conductors associated with the respective ones of the plurality of windows have respective total magnetic fluxes of unity and the other ones of the plurality of conductors have respective total magnetic fluxes of zero, combining the plurality of localized susceptive coupling vectors into a susceptance coupling matrix, and transforming the susceptance coupling matrix so that the susceptance coupling matrix is symmetrical, comprising: comparing a first susceptive coupling element determined for a first one of the plurality of conductors with respect to a second one of the plurality of conductors with a second susceptive coupling element determined for the second one of the plurality of conductors with respect to the first one of the plurality of conductors; selecting one of the first and the second susceptive coupling elements having a smallest magnitude; and replacing the non-selected susceptive coupling element with the selected susceptive coupling element in the susceptance coupling matrix.
