Summary:RC tree approximation is a computationally simple method
for calculating the signal delay of MOS circuits with several states of
fanout. The author derives a formal solution of RC tree
equations. Based on this solution, it is shown that even though
waveforms found using RC tree approximation are inaccurate,
delays are exact. The author derives the dependence of the delays on
input waveforms and initial conditions, and he introduces criteria for
estimating the accuracy of single-time-constant waveform approximation
