    Tuning of diagonal (45°) traces and diff pairs fails

    bollenberg

      Hello everybody,

       

      I am routing a ddr3-design with matched length of the different busses. The length matching function works well. Although sometimes the tuning meter is not shown if I shove a trace. But this is rather sporadic.

       

      Currently, I have two little problems and I do not know the reason:

       

      1. If I mark a differential pair and would tune it by "manual tune", nothing happend. Even it is not displayed a white frame which marked the tuning area. Therefore I have to create the meander structure by hand...   Is it possible, that tuning of differential pairs are not supported by EE7.9.5?

       

      2. If I want to tune a diagonal trace, the tuning structure is only created orthogonally:

       

      What could be the reason, that the structure is not created diagonal like this:

      Is there any special configuration in the editor control necessary?

       

      Thank you very much for your help.
