Just search "differential" then look under "Forums": [https://easyeda.com/forum/topic/Differential-Signal-Layout-be74f31775ed4172b90a5f366590fd15](https://easyeda.com/forum/topic/Differential-Signal-Layout-be74f31775ed4172b90a5f366590fd15) which includes a link to: [https://easyeda.com/forum/topic/Forecast-Tracks-length-Tuning-is-under-developing-d8b2266d6ecb430eaa5c27d6e1b17b54](https://easyeda.com/forum/topic/Forecast-Tracks-length-Tuning-is-under-developing-d8b2266d6ecb430eaa5c27d6e1b17b54)

Thank you very much Andy !    I did not see the post from Eric. By the way, it seems not to avoid obstacles: ![diff_route.jpg](//image.easyeda.com/pullimage/cFJsK7ob1t4QTvKO0risefl1Ry1osZYOsUQ0ec84.jpeg) Here it routed over the ground pad of a board edge SMA connector. Many Thanks ! rudi

I made this particular project Public: [https://easyeda.com/luudee/usb-3-to-sma](https://easyeda.com/luudee/usb-3-to-sma) I worked around the above issue, by: 1) moving the SMA connectors inside. 2) Then routing the differential signals. 3) locking the traces. 4) Moving the SMA connectors back. 5) Adding a small trace from the SMA connector to the differential signal. It looks good now!~~~~ rudi
