Abstract:
1. A method for determining at least one of a signal reflection, a signal transmission, and a signal coupling among vias in a multi-via electronic package, wherein said electronic package comprises a plurality of vias and at least two parallel layers, comprising the steps of: (a) creating a model of the electronic package as an interior problem and an exterior problem, relative to the at least two parallel layers; (b) determining parameters relating to the vias and the parallel planes corresponding to the at least two parallel layers for use in solving said interior problem and said exterior problem; (c) solving the interior problem to determine a first property of the model based on the parameters that were determined, such that the interior problem is solved by: (d) using the first property and the parameters to solve the exterior problem, to determine a second property of the model; (e) using the second property to determine at least one result selected from the group consisting of: the signal reflection, the signal transmission, and the signal coupling among vias in the electronic structure; and (f) having determined the at least one result, executing at least one step selected from the group consisting of the following steps:
