—This paper introduces the first comprehensive and accurate compact resistance–inductance–capacitance– conductance (RLCG) model for through-silicon vias (TSVs) in 3-D ICs valid from low-to high-frequency regimes, with consideration of the MOS effect in silicon, the alternating-current (ac) conduction in silicon, the skin effect in TSV metal, and the eddy(More)
—Through-silicon vias (TSVs) in 3-D integrated circuits (ICs), which are used for connecting different active layers, introduce an important source of coupling noise arising from electrical coupling between TSVs and the active regions. This paper, for the first time, presents compact models based on a fully analytical approach for the electrical coupling(More)
We discuss interconnect parasitic extraction in the nanometer domain using the ITRS 2005 roadmap for future technology generations. Resistance becomes the dominant contribution for timing for local wires at 65 nm and beyond, a major qualitative change. For scaled wires, maintaining global wire routes within 1 clock period is expensive in terms of power(More)
—We propose an efficient method to accurately compute the frequency-dependent impedance of VLSI interconnects in the presence of multilayer conductive substrates. The resulting accuracy (errors less than 3%) and CPU time reduction (more than an order of magnitude) emerge from three different ingredients: a 2-D Green's function approach with the correct(More)
We propose a computationally efficient method to calculate, with high accuracy, the mutual impedance between two wires in the presence of multilayer substrates, as needed for high frequency CAD applications. The resulting accuracy (errors smaller than 2%) and CPU time reduction (factors of seven) emerge from three different ingredients: a two dimensional(More)
We present an efficient and scalable framework for the generation of guaranteed passive compact dynamical models for multiport structures. The proposed algorithm enforces passivity using frequency independent linear matrix inequalities, as opposed to the existing optimization based algorithms which enforce passivity using computationally expensive frequency(More)
