Analyzing Crosstalk and Ground Bounce in Multiconduc

Analyzing Crosstalk and Ground
Bounce in Multiconductor Systems
Using SPICE Circuit Simulations
ABSTRACT
Unwanted coupling within electronic systems in the form of
crosstalk (electric or magnetic coupling between circuits)
and ground bounce (common impedance coupling due to
shared ground conductors) can threaten the operation of
high-speed digital systems by causing false triggering. This
paper investigates the mechanisms causing crosstalk and
ground bounce, derives a practical equivalent circuit that
can be used to model their behavior in multiconductor
systems, and demonstrates a useful guideline for applying
the circuit model to real systems. The equivalent circuit
derived can be used to investigate the behavior of coupled
multiconductor transmission systems with a circuit simulation
tool such as SPICE. Such analysis is applied to a threepin
ground-signal-victim arrangement in order to gain a
qualitative understanding of the factors influencing
crosstalk and ground bounce. A 3 x 3 matrix of pins is also
simulated to demonstrate the typical behavior of a multiconductor
system in which multiple lines may be driven
simultaneously. Some general design advice on minimizing
crosstalk and ground bounce is offered on the basis of
these simulations.
