Hi @panpan_fan,
Thanks for the information. It is highlighting when individual nets are selected, but when we select it through the design manager tab, it remains the same, no change in color whatsoever.
I tried adjusting the highlight intensity from the "Darker and Brighter range bar" under Preferences > Electronics > Color > Highlight. But nothing happens, Top Layer Red and the Bottom Layer Blue, they both remain as it is.
Earlier it was an issue but after some updates the issue was resolved. And now it is back in this latest update.
I am attaching a screenshot wherein you can see the the VCC+ signal is selected under Design Manager but the Net is not highlighted.
Hope this helps. Thanks.
