General
Routing over Voids
Routing over voids not allowed except void around device ball/pin the signal
is routed to.
Noise Coupling
Keep critical high-speed traces away from other signal traces or unrelated
power traces and areas or power supply components
The following figures show the common high-speed interface signal routing requirements.
