Bob: A possible alternative to your request........ A couple of things to note for this type of extraction. 1. Accurate, 3D field solution is essential- wirebond slope, any angle routing, package balls (width, height, etc), power rings, plane voids and splits, etc... 2. Accounting for bump, bondwire, interconnect, and ball field coupling. Hence, supporting item 1 above. So, with that mentioned, another possibility to extract this type of information is by generating the necessary RLCG matrix to compensate for the self and mutual effects, loss, and so forth. This can be simply done with BandedSymmetricMatrix and/or SparseSymmetricMatrix (or even Circuits models which represent either lumped or distributed models) formats. You can easily extract above with APE (Advanced Package Engineer), which offers combination and direct integration with Ansoft parasitic parameters/TPA and SpecctraQuest for IC Packaging. The result of this integration includes direct extraction from the .mcm and automatically creating either a single line or coupled line parasitic package model (options for controlling coupling, segment decomposition (filaments), trace/plane boundary surfaces ,etc) format that can be directly plugged into SpecctraQuest.
