Signal shielding assignment technique for precharge based logic

摘要

A signal shielding technique that assigns voltage potential to shield wires based on the dominant switching direction of a signal is provided. The dominant switching direction is determined based on pre-charge based logic that drives the signal. By determining the voltage potential the signal is more likely to transition to, the shield wires can be implemented so that a discharge event occurs during the dominant transition. Because the signal is more likely to switch in the dominant switching direction, power supply collapses associated with charging events may be reduced.
