Abstract
The Miller effect, as it applies to VLSI wiring, is well-known: some combinations of signal values may experience apparent wire capacitances that are much larger than the static capacitances. Less well known is the-anti-Miller-effect: that some combinations of signal values may experience apparent wire capacitances that are much lower than the static capacitances. The consequence of the Miller and anti-Miller effects is a spread in wiring delays from maximum to minimum that may be three-to-one or more.The spread in wire delays can play havoc with circuits and design practices that depend on wires having near-constant delays.
