consider SI in their designs. Modern digital circuits can operate up to gigahertz frequencies with rise times in the order of fifty picoseconds. At these speeds‚ a carelessly designed PCB trace only needs to be an inch or so long before it radiates. Radiating traces create voltage‚ timing and interference problems not only on that line‚ but also across the entire board and even across adjacent boards.
