Abstract:
1. A computer-implemented method of simulating a signal integrity structure excitable via transmission lines, the method comprising the steps of: (a) constructing by a processor and storing in memory coupled to the processor, a plurality of stable processed modes for the signal integrity structure, each stable processed mode comprising a linear combination of a plurality of eigenmodes, the construction of each stable processed mode comprising: (i) computation of at least one of a first matrix T and a second matrix U, the first matrix T being computed by integrating electric fields of the eigenmodes over a first path between a corresponding terminal and a reference terminal and the second matrix U being computed by integrating magnetic fields of the eigenmodes over a second path around the corresponding terminal; (ii) computation of a transformation matrix R using at least one of the first matrix T and the second matrix U, and (iii) modifying the eigenmodes using the transformation matrix R to obtain the stable processed mode; and (b) computationally simulating by the processor the signal integrity structure using the plurality of stable processed modes.
