Crosstalk

Interference between signals
popularity

Description

Due to process-technology scaling, the spacing between adjacent interconnects shrinks, which leads to an increase in coupling capacitance between wires. Switching on one signal, called the aggressor, can influence another signal, called the victim. This may, in the worst cases, cause a change in value of the victim, or it could delay a signal transition affecting timing. This is classified as a signal integrity issue.
