SIGNAL WIRE SHIELDING TECHNIQUE |
摘要 |
A technique for actively shielding a signal such that a signal driver of the signal only participates in discharge events is provided. Because the signal driver only participates in discharge events, the signal driver is non-interacting with respect to other driver devices. Shield wires are set such that an active transition on the signal causes a discharge of capacitance between the signal and the shield wires. 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. |
