AD21 Diff Pair Length Match Problem

[ibocakir06]

Hi everyone,

I use Altium Designer 21 then I have a problem.

My problem is I can't do interactive diff pair length tuning. (I can do normal interactive length tuning).

I attached a picture it said net length zero and it said different picoseconds. I have a rule for length matching. Does anyone know that how can I solve these problems?

Thanks in advance.

Hi again,

We solved the problem. The DIFF PAIR classes are missing for proper diff pair length tuning.

Thank you
