摘要：A layered structure is divided into a plurality of regions. Transmission lineequivalents (Green's functions) in the spectral domain are formed between all regionswithin the layered structure. The spectral domain Greens' function are converted to thespatial domain using a near field and a far field computed for those regions part of acomponent within the layered structure. The far field is extracted from a compresseddatabase computed from the transmission line equivalents and descriptive of the layeredstructure. The near field is computed using a prioritization mechanism. Priority is assignedin accordance with the amplitude of a source and the length of the path between regionsof interest.
Once the physical characteristics of the layers used in the fabrication process of the ICare identified, the database used for computation of the far field is compiled andcompressed, and remains unchanged for each new parameter extraction. Thus,
compressed, layered Green's functions in the database decouple the computation of thefar field from the layer structure and circuit geometry, minimizing computation time.
