Need help regarding Differential Pair Routing on PCB Editor 17.4

ManjunathMysore

Hi
I'm a newbie, I need suggestions regarding differential pair

I have completed most of my routing on a 4 layer board and not routed the differential pair which I had kept it later to route, but now I'm unable to route the differential pair according to the rules of the differential pairs of USB,Ethernet and CAN protocols as all the above protocols should get reference plane and there should be no single trace passing under the differential pair, but as I have already routed there are many traces which are getting crossed over in different layers.

How can I move forward?

Please suggest

    Hi,

    That seems to be a tricky situation.

    If it were me, I would:

    1. Perform some routing cleanups in the areas where the differential pairs need to be routed.

    2. Create constraints in Constraint Manager for the differential pairs (e.g., spacing, width, and reference plane requirements).

    3. Identify rule violations using DRC Check.

    4. Move conflicting traces or reassign them to different layers to avoid overlaps.

    5. Route the differential pairs, ensuring reference plane continuity.

    6. Verify the final routing with a DRC check.
