Summary: | For the past two decades, the feature size in the
integrated circuits industry has been shrinking continuously.
The higher number of gates integrated on a die has been
translated into soaring demand for on-chip communication.
Different multilevel signaling techniques with and without bus
encoding or error control coding have been proposed to deal
with the tradeoffs between reliability and power consumption.
However, the signal integrity analysis to evaluate these
techniques has been often performed based on pessimistic static
noise margins. By applying dynamic noise margins, in this
paper, we propose a new method to model the receivers in 4-
PAM signaling scheme as one of popular alternatives for binary
signaling. The outcome of this research demonstrates significant
improvement in predicting the reliability performance of the
chosen signaling scheme. The more realistic signal integrity
analysis presented here can be utilized in favor of various design
optimizations, for example, shorter spaces between wires, longer
interconnects, faster transitions and lower signaling voltages. |
