P. Maffezzoni et A. Brambilla, Efficient method for simulating time delays of distributed interconnections in VLSI circuits, ELECTR LETT, 35(12), 1999, pp. 976-977
A new technique is described for modelling a general distributed RC line th
rough a simple lumped net. This reduced order model approximates both the l
ong time voltage response and the input loading effect of the line. The pro
posed method has the advantage of allowing the employment of circuit simula
tors such as SPICE to evaluate interconnect delays in complex layouts.
