A simple analytical model based on Delayed Quadratic (DQ) Transfer Function approximation is proposed for estimating waveforms of inductive single-line interconnects in VLSI's. An expression for overshoot voltage is derived by the model within 17% error for the line width less than 10 times the minimum line width and typical input signal. A delay expression is also proposed within 15% for the same condition. The strength of the inductive effect is shown to be expressed by a closed-form expression, A = 2(L(CT + 0.5C))1/2/(RT(CT + CJ) + RTC + RCT + 0.4RC). By using the criteria, a scaling trend of inductive effects in VLSI's is discussed. It is shown that the inductive effect of single-line, minimum-width VLSI interconnect peaks off at 90 nm based on the ITRS predicted para-meters.
