SUMMARY
The discussion clarifies why short circuit current is often neglected when calculating the delay of a CMOS inverter, particularly during the fall time delay. It emphasizes that during the brief period when both the upper and lower transistors conduct, the short circuit current is constrained by the inductance and resistance of the circuit path. The impact of this current is minimal on the overall delay calculation, as the signal propagation remains unaffected, and any minor influences are accounted for by adjusting the RC parameters of the model.
