Importance of inductance and inductive coupling for on-chip wiring


The importance of inductance and inductive coupling for accurate delay and crosstalk prediction in on-chip interconnections is investigated experimentally for the top three layers in a five-layer wiring structure and guidelines are formulated. In-plane and between-plane crosstalk and delay dependence on driver and receiver circuit device sizes and line lengths and width are analyzed with representative CMOS circuits. Simplified constant-parameter, distributed coupled-line RLC-circuit representation that approximates the waveforms predicted with frequency-dependent line parameters is shown feasible.
