What kinds of PCBs are you thinking to auto-route?If you are talking about a typical hobbyist board with very low frequency switching, the problem is relatively simple, particularly if you allow more than two layer boards. Even there you can create massive problems if you do power distribution wrong.On the other hand, if you are trying to do something with high frequencies, the problem will be much more difficult. For example, many high speed analog-digital converters use low voltage differential signalling (LVDS) to move data around. Such signals are very sensitive to bad routing since they must be kept very near each other (to avoid creating an inductive loop sensitive to external signals) and must have the same length (to retain common mode rejection). Similarly, RF amplifiers will often oscillate badly or have much lower bandwidth if laid out incorrectly.
