Abstract
A circuit for detecting ground bounce and for using the detection information to reduce data error resulting therefrom is described. In one embodiment an on-chip ground bounce detector circuit detects large ground bounce events caused by the simultaneous switching of I/O buffers of the chip and notifies an on-chip logic circuit of the event The on-chip logic circuit can be implemented to take a variety of actions upon receipt of notification from the detection circuit that a ground bounce has been detected.
