Ground Net suddenly turned to gray color

Kabal

I dont know why suddenly all ground Pins of all chips/connectors turned Gray?

In the color assignment for planes they have different color. why would that happen?

 

Also, another question is, why do I have that light Blue colored rectangle on the power/voltage pins?

(I was assigning before some models and auto/resolving the issues in Model Assignemnt, but I wanted to revert it all back and I still have those blue rectangles which do not go away)

    You have selected the ground net, temporary hightlight is likely white, or you have assigned a colour to the net.

    You have voltage properties assigned to the nets, the SI setup would have required this, they have no rats but do get the squares attached to the connection points - you would need to clear the Voltage assignments to remove them.

     I did not assign color to a net for sure, and I did not select anything, I made sure everything is deselected.

    Or maybe it is selected and just switched ON as selected? If thats the case how can I totally deselect everything? (or ground net in this case)

     

     Regarding voltage, I go now to Analyze->Model Assignment, go through all tabs and press "Clear All Model Assignments", Nothing helps. Where exactly is VOLTAGE assignment located?

     OK finally got it working, it was in:

    CM, Properties->Net, General Properties

     there I saw 3V, removed it. Squares gone.

    then I saw GND with red triangle mark on it, went to PCB editor, select Ratsnest, right button click->Net->Dehighlight

  • Kabal

     just my 2cents:

    When in the property editor in CM, I see that red triangle indicating that GND is selected, and I right click and do "Deselect", it *has* to be deselected! If it does not then its some sort of a bug!

    Which is why, I had to as I described go to Layout, manually select GND Ratsnest and do Net->Dehighlight

     correct me if I am wrong.

    Hi,

    Any chance to have the solution for the same problem in OrCad 2017?

    What's CM? Constraint Manager?

    Kind regards.
