Track meter vs DRC

I’m currently working on a large project with the Jetson Orin. I’m using almost all of its high-speed differential ports.

The problem is the following:

I’ve created a custom rule to make sure that the lengths of the pairs on a bus are equal.

(version 1)
(rule "target length and skew eth"
      (condition "A.NetClass == 'DP_100OHM'")
      (constraint length (min 70.5mm) (opt 71mm) (max 71.5mm))
      (constraint skew (max 1mm)))

With this rule I can control the length of all the ropes that are in that class. And it works well when using the adjustment tool.

The problem is that when I check the rules, it tells me that those tracks are not the correct size, which is false because they are.

I’m a little worried because I don’t know who to believe about the length.


With the track inspector, the lengths also seem to be correct.
