10.7.1.2. Evaluating SignaI Integrity Issues

Signal integrity problems can only really be evaluated in two ways:
  • direct measurement using suitable test equipment like an oscilloscope and probe
  • simulation using a tool like HyperLynx or Allegro PCB SI

Compare signals to the respective electrical specification. You should look for overshoot and undershoot, non-monotonicity, eye height and width, and crosstalk.
