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.
