Internally Connected Pins on Cell Layouts are Not Working

Zeke KJ7NLL

We created a cell footprint for a shield inductor for my HF radio project. The shield has multiple pins, so we assigned all of those pins as cell port 3. When we connect to one of the shield cell ports, it should connect to the other side, but ratlines clearly show that it does not when connecting both shield pins as intended. I tried playing with cell port groups and put both cell port pins in the same group (Group 3) but that did not help. The group type is set to strong and the help page for cell ports says that strong should allow conductivity between pins, but it does not.

You can see from the picture, that the top pin and the bottom pin should be connected, but they already are because they are both port 3. This is a sub-circuit and the light colored iNet in the bottom left corner of the picture is in the sub-circuit, but the dark the dark purple is outside of the sub-circuit. This inductor component has a FET component in the middle of the inductor that switches the inductor. It is a sub-circut because we need to re-use it 18 times in the layout. Here is my first video explaining what we are trying to do:

Thank you for your help!!1

    Hi Zeke,

    Great video!     

    What you are describing should work.   In the picture below you can see there are two pins for port1 and two pins for port2.   The pin group style is "strong" for port1 and "weak" for port2.   As expected, there is no ratline between the two port1 pins and a ratline is shown between the two port2 pins.

    Can you please check to ensure that all of your pins in group 3 are indeed set to use the "strong" setting? 

    If that's not it, then use the link under Help>Email_AWR_Support and send your project and someone will take a look at it for you.

    Best Regards,
    Graeme
