For clock frequencies in the GHz regime and rise times of a few tens of ps, full wave electromagnetic analysis may be required for packaging design and interconnection simulation. Subspace projection approaches, including the Pade via Lanczos (PVL), Krylov, and rational Krylov algorithms, have been used for reduced-order modeling of wide-band electromagnetic systems. A frequency segmentation technique has also been used with the Lanczos algorithm to obtain benchmark data and for scattering parameter extraction from the electromagnetic system. From the various techniques, the combined PVL/frequency segmentation technique is the most promising for efficient and accurate modeling of electromagnetic systems.","PeriodicalId":299335,"journal":{"name":"IEEE 8th Topical Meeting on Electrical Performance of Electronic Packaging (Cat.

This approach is an integral part of the basic PEEC model if the conductor cross-sections are subdivided into cells. This model is efficient for geometries and frequencies where the skin depth is moderate compared to the conductor thickness. However, the computational cost may be too high for the case where the skin depth is a small fraction of the cross-section, especially if it is subdivided into uniform cells. In this paper, a model is presented that is suitable for all frequency regimes of interest, and thus is most appropriate for transient interconnect analysis using a full-wave model denoted as (Lp, P, Z/sub s/, /spl tau/)PEEC, to indicate the inclusion of the complex skin effect model Z/sub s/.","PeriodicalId":299335,"journal":{"name":"IEEE 8th Topical Meeting on Electrical Performance of Electronic Packaging (Cat.

A procedure for optimization of the decoupling capacitors based on the fundamental frequency and harmonic frequencies has been illustrated. The optimized decoupling strategy was then implemented on a dual processor board and was measured on a network analyzer.

To provide a means for designers to correctly decide on a socket or vendor, a standard specification and standard characterization method are necessary. This standard specification will also correctly represent the physical and electrical behavior of the socket. In this paper, a new socket specification is given. To more accurately estimate the socket parasitics, a new 3D modeling method is proposed. A new measurement technique is defined for precisely extracting a socket's model component values. The measurement technique utilizes a de-embedding process and a unique test fixture to ensure the final parasitic values included only the parasitics of the socket. The difference between modeling and measured socket parasitics is within 10%. This technique has been demonstrated and adopted for all Intel socket suppliers.","PeriodicalId":299335,"journal":{"name":"IEEE 8th Topical Meeting on Electrical Performance of Electronic Packaging (Cat.
