WebJan 4, 2024 · In DDR4, memories are routed in Fly-by topology rather than Tree-topology; this was done specially to reduce the reflection caused during high-speed data transfer. The clock (and address) signals in Fly … If you're routing on the inner layers, striplines or dual striplines can be used for differential pairs. Surface traces should be routed as impedance-controlled microstrips. All lines need impedance control to suppress reflections along interconnects and at the receiver. Traces are recommended to … See more Fly-by topology has a daisy chain structure that contains either very short stubs or no stubs whatsoever. Because of that structure, fly-by topology has fewer branches and point-to-point connections. When working with … See more In using fly-by topology, there are some basic guidelines to follow as you route tracks that can help ensure signal integrity. The first is your layer stack arrangement and chip orientation. If the board design has sufficient space, … See more Given the complexity of larger numbers of routes, you should use the schematic as the foundation for your design.
