Abstract
A methodology for predicting incidents of ground bounce and using this information for reducing data error caused thereby is described. In one embodiment, data to be clocked into a plurality of output buffers from a first register is read before it goes to the buffers and a determination is made as to what number of bits B will change state, i.e., from a zero to a one or a one to a zero. B is then compared to a predetermined threshold T. If B is greater than T, a wait state or some other indication is issued when the bits are clocked into the I/O buffers.
