We will add "single trace mode" for diff pairs for the stable version. Currently we are developing the mode.

Differential circuitry is the increased number of traces. So, if none of the advantages are particularly significant in your application, differential signals and the associated routing considerations are not worth the cost in increased area.

Hi!

Is it possible to use the differential pair routing with more than two lines?
It would be cool if i could define 16lines as one pair for routing a bus.
Normally, that's the same functionality as two lines is. Isn't it?

Hope it will work...

It does not work right now yet.

Functionality is similar, but not the same. Trace routing functions were changed in 3.0 to support both single traces and differential pairs and number of signals in those algorithms is not limited. Also it is possible to use majority of diff pair algortihms with slight modification for busses, so I suppose we will add them in minor updates of 3.0. But we should complete high-speed routing first.

Is there a way to remove a meander from a differential pair? For example, create a differential pair and then add two or three meanders on one of the tracks. How does one delete only one of those meanders without affecting the rest of the differential pair and its remaining meanders? If this is not possible without tediously deleting one node at a time, perhaps something like a Remove Meander option could be added to the right-click drop-down menu...

It's quite easy, just drag mender center line (selected at you picture) back to diff pair line, then release mouse button - trace will be optimized and meander will be removed.
We will not add such option as existing meander feature is temporary solution for phase tune and meanders will be added as separate objects which you will be able to move within trace, edit or delete.

Excellent. Thank you for the help.

Okay, thank you for the fast reply!
That would really a cool feature, if that is working with some traces together.
But you're right, it makes sense first to complete the unfinished things.

greetings!
