6.3.2Routing Guidelines
It is recommended to route signals with respect to an adjacent ground plane. If routing signals over power planes, ensure that the signals are referenced to a single power plane voltage level and not multiple levels. For example, you can route signals over a
3.3V plane or a 5 V plane, but do not route the same signal over both planes. If signals are routed over split planes, you must connect the splitting planes with 0.01 µF,
This manual does not repeat all the guidelines that are already stated in the
PCI Local Bus Specification, Rev. 2.2. Refer to the specification when designing a motherboard or an expansion card.
